File

Required Methods

fn append_to( &self, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileOutputStream, Error>

Gets an output stream for appending data to the file. If the file doesn’t already exist it is created.

By default files created are generally readable by everyone, but if you pass FileCreateFlags::PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

Some file systems don’t allow all file names, and may return an IOErrorEnum::InvalidFilename error. If the file is a directory the IOErrorEnum::IsDirectory error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

flags

a set of FileCreateFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileOutputStream, or None on error. Free the returned object with g_object_unref().

fn append_to_async<P: FnOnce(Result<FileOutputStream, Error>) + 'static>( &self, flags: FileCreateFlags, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously opens self for appending.

For more details, see append_to() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call g_file_append_to_finish() to get the result of the operation.

fn append_to_future( &self, flags: FileCreateFlags, io_priority: Priority ) -> Pin<Box_<dyn Future<Output = Result<FileOutputStream, Error>> + 'static>>

fn build_attribute_list_for_copy( &self, flags: FileCopyFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<GString, Error>

Available on crate feature v2_68 only.

fn copy( &self, destination: &impl IsA<File>, flags: FileCopyFlags, cancellable: Option<&impl IsA<Cancellable>>, progress_callback: Option<&mut dyn FnMut(i64, i64)> ) -> Result<(), Error>

fn copy_attributes( &self, destination: &impl IsA<File>, flags: FileCopyFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Copies the file attributes from self to destination.

Normally only a subset of the file attributes are copied, those that are copies in a normal file copy operation (which for instance does not include e.g. owner). However if FileCopyFlags::ALL_METADATA is specified in flags, then all the metadata that is possible to copy is copied. This is useful when implementing move by copy + delete source.

destination

a File to copy attributes to

flags

a set of FileCopyFlags

cancellable

optional Cancellable object, None to ignore

Returns

true if the attributes were copied successfully, false otherwise.

fn create( &self, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileOutputStream, Error>

Creates a new file and returns an output stream for writing to it. The file must not already exist.

By default files created are generally readable by everyone, but if you pass FileCreateFlags::PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If a file or directory with this name already exists the IOErrorEnum::Exists error will be returned. Some file systems don’t allow all file names, and may return an IOErrorEnum::InvalidFilename error, and if the name is to long IOErrorEnum::FilenameTooLong will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

flags

a set of FileCreateFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileOutputStream for the newly created file, or None on error. Free the returned object with g_object_unref().

fn create_async<P: FnOnce(Result<FileOutputStream, Error>) + 'static>( &self, flags: FileCreateFlags, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously creates a new file and returns an output stream for writing to it. The file must not already exist.

For more details, see create() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call g_file_create_finish() to get the result of the operation.

fn create_readwrite( &self, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileIOStream, Error>

Creates a new file and returns a stream for reading and writing to it. The file must not already exist.

By default files created are generally readable by everyone, but if you pass FileCreateFlags::PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If a file or directory with this name already exists, the IOErrorEnum::Exists error will be returned. Some file systems don’t allow all file names, and may return an IOErrorEnum::InvalidFilename error, and if the name is too long, IOErrorEnum::FilenameTooLong will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

Note that in many non-local file cases read and write streams are not supported, so make sure you really need to do read and write streaming, rather than just opening for reading or writing.

flags

a set of FileCreateFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileIOStream for the newly created file, or None on error. Free the returned object with g_object_unref().

fn create_readwrite_async<P: FnOnce(Result<FileIOStream, Error>) + 'static>( &self, flags: FileCreateFlags, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously creates a new file and returns a stream for reading and writing to it. The file must not already exist.

fn delete( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Deletes a file. If the self is a directory, it will only be deleted if it is empty. This has the same semantics as g_unlink().

If self doesn’t exist, IOErrorEnum::NotFound will be returned. This allows for deletion to be implemented avoiding time-of-check to time-of-use races:

g_autoptr(GError) local_error = NULL;
if (!g_file_delete (my_file, my_cancellable, &local_error) &&
    !g_error_matches (local_error, G_IO_ERROR, G_IO_ERROR_NOT_FOUND))
  {
    // deletion failed for some reason other than the file not existing:
    // so report the error
    g_warning ("Failed to delete %s: %s",
               g_file_peek_path (my_file), local_error->message);
  }

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

true if the file was deleted. false otherwise.

fn delete_async<P: FnOnce(Result<(), Error>) + 'static>( &self, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously delete a file. If the self is a directory, it will only be deleted if it is empty. This has the same semantics as g_unlink().

io_priority

cancellable

optional Cancellable object, None to ignore

callback

fn delete_future( &self, io_priority: Priority ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn dup(&self) -> File

Duplicates a File handle. This operation does not duplicate the actual file or directory represented by the File; see g_file_copy() if attempting to copy a file.

dup() is useful when a second handle is needed to the same underlying file, for use in a separate thread (File is not thread-safe). For use within the same thread, use g_object_ref() to increment the existing object’s reference count.

This call does no blocking I/O.

Returns

a new File that is a duplicate of the given File.

fn eject_mountable_with_operation<P: FnOnce(Result<(), Error>) + 'static>( &self, flags: MountUnmountFlags, mount_operation: Option<&impl IsA<MountOperation>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Starts an asynchronous eject on a mountable. When this operation has completed, callback will be called with user_user data, and the operation can be finalized with g_file_eject_mountable_with_operation_finish().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

flags

flags affecting the operation

mount_operation

a MountOperation, or None to avoid user interaction

cancellable

optional Cancellable object, None to ignore

callback

a GAsyncReadyCallback to call when the request is satisfied, or None

fn eject_mountable_with_operation_future( &self, flags: MountUnmountFlags, mount_operation: Option<&impl IsA<MountOperation> + Clone + 'static> ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn enumerate_children( &self, attributes: &str, flags: FileQueryInfoFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileEnumerator, Error>

Gets the requested information about the files in a directory. The result is a FileEnumerator object that will give out FileInfo objects for all the files in the directory.

The attributes value is a string that specifies the file attributes that should be gathered. It is not an error if it’s not possible to read a particular requested attribute from a file - it just won’t be set. attributes should be a comma-separated list of attributes or attribute wildcards. The wildcard “” means all attributes, and a wildcard like “standard::” means all attributes in the standard namespace. An example attribute query be “standard::*,owner::user”. The standard attributes are available as defines, like FILE_ATTRIBUTE_STANDARD_NAME. FILE_ATTRIBUTE_STANDARD_NAME should always be specified if you plan to call FileEnumeratorExt::child() or g_file_enumerator_iterate() on the returned enumerator.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If the file does not exist, the IOErrorEnum::NotFound error will be returned. If the file is not a directory, the IOErrorEnum::NotDirectory error will be returned. Other errors are possible too.

attributes

an attribute query string

flags

a set of FileQueryInfoFlags

cancellable

optional Cancellable object, None to ignore

Returns

A FileEnumerator if successful, None on error. Free the returned object with g_object_unref().

fn equal(&self, file2: &impl IsA<File>) -> bool

fn find_enclosing_mount( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<Mount, Error>

Gets a Mount for the File.

Mount is returned only for user interesting locations, see VolumeMonitor. If the GFileIface for self does not have a mount, error will be set to IOErrorEnum::NotFound and None will be returned.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

a Mount where the self is located or None on error. Free the returned object with g_object_unref().

fn basename(&self) -> Option<PathBuf>

Gets the base name (the last component of the path) for a given File.

If called for the top level of a system (such as the filesystem root or a uri like sftp://host/) it will return a single directory separator (and on Windows, possibly a drive letter).

The base name is a byte string (not UTF-8). It has no defined encoding or rules other than it may not contain zero bytes. If you want to use filenames in a user interface you should use the display name that you can get by requesting the FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with query_info().

This call does no blocking I/O.

Returns

string containing the File’s base name, or None if given File is invalid. The returned string should be freed with g_free() when no longer needed.

fn child(&self, name: impl AsRef<Path>) -> File

Gets a child of self with basename equal to name.

Note that the file with that specific name might not exist, but you can still have a File that points to it. You can use this for instance to create that file.

This call does no blocking I/O.

name

string containing the child’s basename

Returns

a File to a child specified by name. Free the returned object with g_object_unref().

fn child_for_display_name(&self, display_name: &str) -> Result<File, Error>

Gets the child of self for a given display_name (i.e. a UTF-8 version of the name). If this function fails, it returns None and error will be set. This is very useful when constructing a File for a new file and the user entered the filename in the user interface, for instance when you select a directory and type a filename in the file selector.

This call does no blocking I/O.

display_name

string to a possible child

Returns

a File to the specified child, or None if the display name couldn’t be converted. Free the returned object with g_object_unref().

fn parent(&self) -> Option<File>

Gets the parent directory for the self. If the self represents the root directory of the file system, then None will be returned.

This call does no blocking I/O.

Returns

a File structure to the parent of the given File or None if there is no parent. Free the returned object with g_object_unref().

fn parse_name(&self) -> GString

Gets the parse name of the self. A parse name is a UTF-8 string that describes the file such that one can get the File back using File::for_parse_name().

This is generally used to show the File as a nice full-pathname kind of string in a user interface, like in a location entry.

For local files with names that can safely be converted to UTF-8 the pathname is used, otherwise the IRI is used (a form of URI that allows UTF-8 characters unescaped).

This call does no blocking I/O.

Returns

a string containing the File’s parse name. The returned string should be freed with g_free() when no longer needed.

fn path(&self) -> Option<PathBuf>

Gets the local pathname for File, if one exists. If non-None, this is guaranteed to be an absolute, canonical path. It might contain symlinks.

This call does no blocking I/O.

Returns

string containing the File’s path, or None if no such path exists. The returned string should be freed with g_free() when no longer needed.

fn relative_path(&self, descendant: &impl IsA<File>) -> Option<PathBuf>

Gets the path for descendant relative to self.

This call does no blocking I/O.

descendant

input File

Returns

string with the relative path from descendant to self, or None if descendant doesn’t have self as prefix. The returned string should be freed with g_free() when no longer needed.

fn uri(&self) -> GString

Gets the URI for the self.

This call does no blocking I/O.

Returns

a string containing the File’s URI. If the File was constructed with an invalid URI, an invalid URI is returned. The returned string should be freed with g_free() when no longer needed.

fn uri_scheme(&self) -> Option<GString>

Gets the URI scheme for a File. RFC 3986 decodes the scheme as:

URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

Common schemes include “file”, “http”, “ftp”, etc.

The scheme can be different from the one used to construct the File, in that it might be replaced with one that is logically equivalent to the File.

This call does no blocking I/O.

Returns

a string containing the URI scheme for the given File or None if the File was constructed with an invalid URI. The returned string should be freed with g_free() when no longer needed.

fn has_parent(&self, parent: Option<&impl IsA<File>>) -> bool

Checks if self has a parent, and optionally, if it is parent.

If parent is None then this function returns true if self has any parent at all. If parent is non-None then true is only returned if self is an immediate child of parent.

parent

the parent to check for, or None

Returns

true if self is an immediate child of parent (or any parent in the case that parent is None).

fn has_prefix(&self, prefix: &impl IsA<File>) -> bool

Checks whether self has the prefix specified by prefix.

In other words, if the names of initial elements of self’s pathname match prefix. Only full pathname elements are matched, so a path like /foo is not considered a prefix of /foobar, only of /foo/bar.

A File is not a prefix of itself. If you want to check for equality, use g_file_equal().

This call does no I/O, as it works purely on names. As such it can sometimes return false even if self is inside a prefix (from a filesystem point of view), because the prefix of self is an alias of prefix.

prefix

input File

Returns

true if the self’s parent, grandparent, etc is prefix, false otherwise.

fn has_uri_scheme(&self, uri_scheme: &str) -> bool

Checks to see if a File has a given URI scheme.

This call does no blocking I/O.

uri_scheme

a string containing a URI scheme

Returns

true if File’s backend supports the given URI scheme, false if URI scheme is None, not supported, or File is invalid.

fn is_native(&self) -> bool

Checks to see if a file is native to the platform.

A native file is one expressed in the platform-native filename format, e.g. “C:\Windows” or “/usr/bin/”. This does not mean the file is local, as it might be on a locally mounted remote filesystem.

On some systems non-native files may be available using the native filesystem via a userspace filesystem (FUSE), in these cases this call will return false, but path() will still return a native path.

This call does no blocking I/O.

Returns

true if self is native

fn load_bytes( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(Bytes, Option<GString>), Error>

Loads the contents of self and returns it as glib::Bytes.

If self is a resource:// based URI, the resulting bytes will reference the embedded resource instead of a copy. Otherwise, this is equivalent to calling load_contents() and [glib::Bytes::new_take()][crate::glib::Bytes::new_take()].

For resources, etag_out will be set to None.

The data contained in the resulting glib::Bytes is always zero-terminated, but this is not included in the glib::Bytes length. The resulting glib::Bytes should be freed with g_bytes_unref() when no longer in use.

cancellable

a Cancellable or None

Returns

a glib::Bytes or None and error is set

etag_out

a location to place the current entity tag for the file, or None if the entity tag is not needed

fn load_bytes_async<P: FnOnce(Result<(Bytes, Option<GString>), Error>) + 'static>( &self, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously loads the contents of self as glib::Bytes.

If self is a resource:// based URI, the resulting bytes will reference the embedded resource instead of a copy. Otherwise, this is equivalent to calling load_contents_async() and [glib::Bytes::new_take()][crate::glib::Bytes::new_take()].

callback should call g_file_load_bytes_finish() to get the result of this asynchronous operation.

See load_bytes() for more information.

cancellable

a Cancellable or None

callback

a GAsyncReadyCallback to call when the request is satisfied

fn load_bytes_future( &self ) -> Pin<Box_<dyn Future<Output = Result<(Bytes, Option<GString>), Error>> + 'static>>

fn load_contents( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(Vec<u8>, Option<GString>), Error>

Loads the content of the file into memory. The data is always zero-terminated, but this is not included in the resultant length. The returned contents should be freed with g_free() when no longer needed.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

true if the self’s contents were successfully loaded. false if there were errors.

contents

a location to place the contents of the file

etag_out

a location to place the current entity tag for the file, or None if the entity tag is not needed

fn load_contents_async<P: FnOnce(Result<(Vec<u8>, Option<GString>), Error>) + 'static>( &self, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Starts an asynchronous load of the self’s contents.

For more details, see load_contents() which is the synchronous version of this call.

When the load operation has completed, callback will be called with user data. To finish the operation, call g_file_load_contents_finish() with the AsyncResult returned by the callback.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

fn load_contents_future( &self ) -> Pin<Box_<dyn Future<Output = Result<(Vec<u8>, Option<GString>), Error>> + 'static>>

fn make_directory( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Creates a directory. Note that this will only create a child directory of the immediate parent directory of the path or URI given by the File. To recursively create directories, see make_directory_with_parents(). This function will fail if the parent directory does not exist, setting error to IOErrorEnum::NotFound. If the file system doesn’t support creating directories, this function will fail, setting error to IOErrorEnum::NotSupported.

For a local File the newly created directory will have the default (current) ownership and permissions of the current process.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

true on successful creation, false otherwise.

fn make_directory_async<P: FnOnce(Result<(), Error>) + 'static>( &self, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously creates a directory.

io_priority

the [I/O priority][io-priority] of the request

cancellable

optional Cancellable object, None to ignore

callback

a GAsyncReadyCallback to call when the request is satisfied

fn make_directory_future( &self, io_priority: Priority ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn make_directory_with_parents( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Creates a directory and any parent directories that may not exist similar to ‘mkdir -p’. If the file system does not support creating directories, this function will fail, setting error to IOErrorEnum::NotSupported. If the directory itself already exists, this function will fail setting error to IOErrorEnum::Exists, unlike the similar g_mkdir_with_parents().

For a local File the newly created directories will have the default (current) ownership and permissions of the current process.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

true if all directories have been successfully created, false otherwise.

fn make_symbolic_link( &self, symlink_value: impl AsRef<Path>, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Creates a symbolic link named self which contains the string symlink_value.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

symlink_value

a string with the path for the target of the new symlink

cancellable

optional Cancellable object, None to ignore

Returns

true on the creation of a new symlink, false otherwise.

fn monitor( &self, flags: FileMonitorFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileMonitor, Error>

Obtains a file or directory monitor for the given file, depending on the type of the file.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

flags

a set of FileMonitorFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileMonitor for the given self, or None on error. Free the returned object with g_object_unref().

fn monitor_directory( &self, flags: FileMonitorFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileMonitor, Error>

Obtains a directory monitor for the given file. This may fail if directory monitoring is not supported.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

It does not make sense for flags to contain FileMonitorFlags::WATCH_HARD_LINKS, since hard links can not be made to directories. It is not possible to monitor all the files in a directory for changes made via hard links; if you want to do this then you must register individual watches with monitor().

flags

a set of FileMonitorFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileMonitor for the given self, or None on error. Free the returned object with g_object_unref().

fn monitor_file( &self, flags: FileMonitorFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileMonitor, Error>

Obtains a file monitor for the given file. If no file notification mechanism exists, then regular polling of the file is used.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If flags contains FileMonitorFlags::WATCH_HARD_LINKS then the monitor will also attempt to report changes made to the file via another filename (ie, a hard link). Without this flag, you can only rely on changes made through the filename contained in self to be reported. Using this flag may result in an increase in resource usage, and may not have any effect depending on the FileMonitor backend and/or filesystem type.

flags

a set of FileMonitorFlags

cancellable

optional Cancellable object, None to ignore

Returns

a FileMonitor for the given self, or None on error. Free the returned object with g_object_unref().

fn mount_enclosing_volume<P: FnOnce(Result<(), Error>) + 'static>( &self, flags: MountMountFlags, mount_operation: Option<&impl IsA<MountOperation>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Starts a mount_operation, mounting the volume that contains the file self.

When this operation has completed, callback will be called with user_user data, and the operation can be finalized with g_file_mount_enclosing_volume_finish().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

fn mount_mountable<P: FnOnce(Result<File, Error>) + 'static>( &self, flags: MountMountFlags, mount_operation: Option<&impl IsA<MountOperation>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Mounts a file of type G_FILE_TYPE_MOUNTABLE. Using mount_operation, you can request callbacks when, for instance, passwords are needed during authentication.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

When the operation is finished, callback will be called. You can then call g_file_mount_mountable_finish() to get the result of the operation.

fn open_readwrite( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileIOStream, Error>

Opens an existing file for reading and writing. The result is a FileIOStream that can be used to read and write the contents of the file.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If the file does not exist, the IOErrorEnum::NotFound error will be returned. If the file is a directory, the IOErrorEnum::IsDirectory error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on. Note that in many non-local file cases read and write streams are not supported, so make sure you really need to do read and write streaming, rather than just opening for reading or writing.

Exactly like path(), but caches the result via [ObjectExt::set_qdata_full()][crate::glib::prelude::ObjectExt::set_qdata_full()]. This is useful for example in C applications which mix g_file_* APIs with native ones. It also avoids an extra duplicated string when possible, so will be generally more efficient.

This call does no blocking I/O.

Returns

string containing the File’s path, or None if no such path exists. The returned string is owned by self.

fn poll_mountable<P: FnOnce(Result<(), Error>) + 'static>( &self, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Polls a file of type FileType::Mountable.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

When the operation is finished, callback will be called. You can then call g_file_mount_mountable_finish() to get the result of the operation.

cancellable

optional Cancellable object, None to ignore

callback

a GAsyncReadyCallback to call when the request is satisfied, or None

fn poll_mountable_future( &self ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn query_default_handler( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<AppInfo, Error>

Returns the AppInfo that is registered as the default application to handle the file specified by self.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

a AppInfo if the handle was found, None if there were errors. When you are done with it, release it with g_object_unref()

fn query_default_handler_async<P: FnOnce(Result<AppInfo, Error>) + 'static>( &self, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Available on crate feature v2_60 only.

fn query_exists(&self, cancellable: Option<&impl IsA<Cancellable>>) -> bool

Utility function to check if a particular file exists. This is implemented using query_info() and as such does blocking I/O.

Note that in many cases it is racy to first check for file existence and then execute something based on the outcome of that, because the file might have been created or removed in between the operations. The general approach to handling that is to not check, but just do the operation and handle the errors as they come.

As an example of race-free checking, take the case of reading a file, and if it doesn’t exist, creating it. There are two racy versions: read it, and on error create it; and: check if it exists, if not create it. These can both result in two processes creating the file (with perhaps a partially written file as the result). The correct approach is to always try to create the file with create() which will either atomically create the file or fail with a IOErrorEnum::Exists error.

However, in many cases an existence check is useful in a user interface, for instance to make a menu item sensitive/insensitive, so that you don’t have to fool users that something is possible and then just show an error dialog. If you do this, you should make sure to also handle the errors that can happen due to races when you execute the operation.

cancellable

optional Cancellable object, None to ignore

Returns

true if the file exists (and can be detected without error), false otherwise (or if cancelled).

fn query_file_type( &self, flags: FileQueryInfoFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> FileType

Utility function to inspect the FileType of a file. This is implemented using query_info() and as such does blocking I/O.

The primary use case of this method is to check if a file is a regular file, directory, or symlink.

flags

a set of FileQueryInfoFlags passed to query_info()

cancellable

optional Cancellable object, None to ignore

Returns

The FileType of the file and FileType::Unknown if the file does not exist

fn query_filesystem_info( &self, attributes: &str, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileInfo, Error>

Similar to query_info(), but obtains information about the filesystem the self is on, rather than the file itself. For instance the amount of space available and the type of the filesystem.

The attributes value is a string that specifies the attributes that should be gathered. It is not an error if it’s not possible to read a particular requested attribute from a file - it just won’t be set. attributes should be a comma-separated list of attributes or attribute wildcards. The wildcard “” means all attributes, and a wildcard like “filesystem::” means all attributes in the filesystem namespace. The standard namespace for filesystem attributes is “filesystem”. Common attributes of interest are FILE_ATTRIBUTE_FILESYSTEM_SIZE (the total size of the filesystem in bytes), FILE_ATTRIBUTE_FILESYSTEM_FREE (number of bytes available), and FILE_ATTRIBUTE_FILESYSTEM_TYPE (type of the filesystem).

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If the file does not exist, the IOErrorEnum::NotFound error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

attributes

cancellable

optional Cancellable object, None to ignore

Returns

fn query_filesystem_info_async<P: FnOnce(Result<FileInfo, Error>) + 'static>( &self, attributes: &str, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Asynchronously gets the requested information about the filesystem that the specified self is on. The result is a FileInfo object that contains key-value attributes (such as type or size for the file).

For more details, see query_filesystem_info() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call g_file_query_info_finish() to get the result of the operation.

fn query_info( &self, attributes: &str, flags: FileQueryInfoFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileInfo, Error>

Gets the requested information about specified self. The result is a FileInfo object that contains key-value attributes (such as the type or size of the file).

The attributes value is a string that specifies the file attributes that should be gathered. It is not an error if it’s not possible to read a particular requested attribute from a file - it just won’t be set. attributes should be a comma-separated list of attributes or attribute wildcards. The wildcard “” means all attributes, and a wildcard like “standard::” means all attributes in the standard namespace. An example attribute query be “standard::*,owner::user”. The standard attributes are available as defines, like FILE_ATTRIBUTE_STANDARD_NAME.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

For symlinks, normally the information about the target of the symlink is returned, rather than information about the symlink itself. However if you pass FileQueryInfoFlags::NOFOLLOW_SYMLINKS in flags the information about the symlink itself will be returned. Also, for symlinks that point to non-existing files the information about the symlink itself will be returned.

If the file does not exist, the IOErrorEnum::NotFound error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

fn query_info_future( &self, attributes: &str, flags: FileQueryInfoFlags, io_priority: Priority ) -> Pin<Box_<dyn Future<Output = Result<FileInfo, Error>> + 'static>>

fn query_settable_attributes( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileAttributeInfoList, Error>

Obtain the list of settable attributes for the file.

Returns the type and full attribute name of all the attributes that can be set on this file. This doesn’t mean setting it will always succeed though, you might get an access failure, or some specific file may not support a specific attribute.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

a FileAttributeInfoList describing the settable attributes. When you are done with it, release it with g_file_attribute_info_list_unref()

fn query_writable_namespaces( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileAttributeInfoList, Error>

Obtain the list of attribute namespaces where new attributes can be created by a user. An example of this is extended attributes (in the “xattr” namespace).

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

a FileAttributeInfoList describing the writable namespaces. When you are done with it, release it with g_file_attribute_info_list_unref()

fn read( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileInputStream, Error>

Opens a file for reading. The result is a FileInputStream that can be used to read the contents of the file.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If the file does not exist, the IOErrorEnum::NotFound error will be returned. If the file is a directory, the IOErrorEnum::IsDirectory error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

cancellable

Returns

FileInputStream or None on error. Free the returned object with g_object_unref().

fn read_async<P: FnOnce(Result<FileInputStream, Error>) + 'static>( &self, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

fn read_future( &self, io_priority: Priority ) -> Pin<Box_<dyn Future<Output = Result<FileInputStream, Error>> + 'static>>

fn replace( &self, etag: Option<&str>, make_backup: bool, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileOutputStream, Error>

Returns an output stream for overwriting the file, possibly creating a backup copy of the file first. If the file doesn’t exist, it will be created.

This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.

By default files created are generally readable by everyone, but if you pass FileCreateFlags::PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

If you pass in a non-None etag value and self already exists, then this value is compared to the current entity tag of the file, and if they differ an IOErrorEnum::WrongEtag error is returned. This generally means that the file has been changed since you last read it. You can get the new etag from FileOutputStreamExt::etag() after you’ve finished writing and closed the FileOutputStream. When you load a new file you can use FileInputStreamExt::query_info() to get the etag of the file.

If make_backup is true, this function will attempt to make a backup of the current file before overwriting it. If this fails a IOErrorEnum::CantCreateBackup error will be returned. If you want to replace anyway, try again with make_backup set to false.

If the file is a directory the IOErrorEnum::IsDirectory error will be returned, and if the file is some other form of non-regular file then a IOErrorEnum::NotRegularFile error will be returned. Some file systems don’t allow all file names, and may return an IOErrorEnum::InvalidFilename error, and if the name is to long IOErrorEnum::FilenameTooLong will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

etag

fn replace_contents( &self, contents: &[u8], etag: Option<&str>, make_backup: bool, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<Option<GString>, Error>

Replaces the contents of self with contents of length bytes.

If etag is specified (not None), any existing file must have that etag, or the error IOErrorEnum::WrongEtag will be returned.

If make_backup is true, this function will attempt to make a backup of self. Internally, it uses replace(), so will try to replace the file contents in the safest way possible. For example, atomic renames are used when replacing local files’ contents.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

The returned new_etag can be used to verify that the file hasn’t changed the next time it is saved over.

fn replace_readwrite( &self, etag: Option<&str>, make_backup: bool, flags: FileCreateFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<FileIOStream, Error>

Returns an output stream for overwriting the file in readwrite mode, possibly creating a backup copy of the file first. If the file doesn’t exist, it will be created.

For details about the behaviour, see replace() which does the same thing but returns an output stream only.

Note that in many non-local file cases read and write streams are not supported, so make sure you really need to do read and write streaming, rather than just opening for reading or writing.

fn resolve_relative_path(&self, relative_path: impl AsRef<Path>) -> File

Resolves a relative path for self to an absolute path.

This call does no blocking I/O.

If the relative_path is an absolute path name, the resolution is done absolutely (without taking self path as base).

relative_path

fn set_attributes_from_info( &self, info: &FileInfo, flags: FileQueryInfoFlags, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Tries to set all attributes in the FileInfo on the target values, not stopping on the first error.

If there is any error during this operation then error will be set to the first error. Error on particular fields are flagged by setting the “status” field in the attribute value to FileAttributeStatus::ErrorSetting, which means you can also detect further errors.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

fn set_display_name( &self, display_name: &str, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<File, Error>

Renames self to the specified display name.

The display name is converted from UTF-8 to the correct encoding for the target filesystem if possible and the self is renamed to this.

If you want to implement a rename operation in the user interface the edit name (FILE_ATTRIBUTE_STANDARD_EDIT_NAME) should be used as the initial value in the rename widget, and then the result after editing should be passed to set_display_name().

On success the resulting converted filename is returned.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

display_name

a string

cancellable

optional Cancellable object, None to ignore

Returns

a File specifying what self was renamed to, or None if there was an error. Free the returned object with g_object_unref().

fn stop_mountable_future( &self, flags: MountUnmountFlags, mount_operation: Option<&impl IsA<MountOperation> + Clone + 'static> ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn supports_thread_contexts(&self) -> bool

Checks if self supports [thread-default contexts][g-main-context-push-thread-default-context]. If this returns false, you cannot perform asynchronous operations on self in a thread that has a thread-default context.

Returns

Whether or not self supports thread-default contexts.

fn trash( &self, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(), Error>

Sends self to the “Trashcan”, if possible. This is similar to deleting it, but the user can recover it before emptying the trashcan. Not all file systems support trashing, so this call can return the IOErrorEnum::NotSupported error. Since GLib 2.66, the x-gvfs-notrash unix mount option can be used to disable trash() support for certain mounts, the IOErrorEnum::NotSupported error will be returned in that case.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore

Returns

true on successful trash, false otherwise.

fn unmount_mountable_with_operation<P: FnOnce(Result<(), Error>) + 'static>( &self, flags: MountUnmountFlags, mount_operation: Option<&impl IsA<MountOperation>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Unmounts a file of type FileType::Mountable.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

When the operation is finished, callback will be called. You can then call g_file_unmount_mountable_finish() to get the result of the operation.

flags

flags affecting the operation

mount_operation
