Documentation

Using

We recommend using crates from crates.io, as demonstrated here.

If you want to track the bleeding edge, use the git dependency instead:

[dependencies]
gio = { git = "https://github.com/gtk-rs/gtk-rs-core.git", package = "gio" }

Avoid mixing versioned and git crates like this:

[dependencies]
gio = "0.13"
gio = { git = "https://github.com/gtk-rs/gtk-rs-core.git", package = "gio" }

Structs

Action represents a single named action.

ActionGroup represents a group of actions. Actions can be used to expose functionality in a structured way, either from one part of a program to another, or to the outside world. Action groups are often used together with a MenuModel that provides additional representation data for displaying the actions to the user, e.g. in a menu.

The GActionMap interface is implemented by ActionGroup implementations that operate by containing a number of named Action instances, such as SimpleActionGroup.

Integrating the launch with the launching application. This is used to handle for instance startup notification and launching the new application on the same screen as the launching window.

A Application is the foundation of an application. It wraps some low-level platform-specific services and is intended to act as the foundation for higher-level application classes such as GtkApplication or MxApplication. In general, you should not use this class outside of a higher level framework.

DBusServer is a helper for listening to and accepting D-Bus connections. This can be used to create a new D-Bus server, allowing two peers to use the D-Bus protocol for their own specialized communication. A server instance provided in this way will not perform message routing or implement the org.freedesktop.DBus interface.

Flags used when creating a DBusServer.

EmblemedIcon is an implementation of Icon that supports adding an emblem to an icon. Adding multiple emblems to an icon is ensured via EmblemedIconExt::add_emblem().

File is a high level abstraction for manipulating files on a virtual file system. GFiles are lightweight, immutable objects that do no I/O upon creation. It is necessary to understand that File objects do not represent files, merely an identifier for a file. All file content I/O is implemented as streaming operations (see InputStream and OutputStream).

Determines if a string matches a file attribute.

Flags used when copying or moving files.

Flags used when an operation may create a file.

FileEnumerator allows you to operate on a set of GFiles, returning a FileInfo structure for each file enumerated (e.g. FileExt::enumerate_children() will return a FileEnumerator for each of the children within a directory).

GFileIOStream provides io streams that both read and write to the same file handle.

FileIcon specifies an icon by pointing to an image file to be used as icon.

GFileInputStream provides input streams that take their content from a file.

Flags that can be used with FileExt::measure_disk_usage().

Monitors a file or directory for changes.

Flags used to set what a FileMonitor will watch for.

Flags used when querying a FileInfo.

Completes partial file and directory names given a partial string by looking in the file system for clues. Can return a list of possible completion strings for widget implementations.

Base class for input stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.

Base class for output stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.

GIOStream represents an object that has both read and write streams. Generally the two streams act as separate input and output streams, but they share some common resources and state. For instance, for seekable streams, both streams may use the same position.

GIOStreamSpliceFlags determine how streams should be spliced.

Icon is a very minimal interface for icons. It provides functions for checking the equality of two icons, hashing of icons and serializing an icon to and from strings.

InetAddress represents an IPv4 or IPv6 internet address. Use ResolverExt::lookup_by_name() or ResolverExt::lookup_by_name_async() to look up the InetAddress for a hostname. Use ResolverExt::lookup_by_address() or ResolverExt::lookup_by_address_async() to look up the hostname for a InetAddress.

InetAddressMask represents a range of IPv4 or IPv6 addresses described by a base address and a length indicating how many bits of the base address are relevant for matching purposes. These are often given in string form. Eg, “10.0.0.0/8”, or “fe80::/10”.

An IPv4 or IPv6 socket address; that is, the combination of a InetAddress and a port number.

Initable is implemented by objects that can fail during initialization. If an object implements this interface then it must be initialized as the first thing after construction, either via InitableExt::init() or g_async_initable_init_async() (the latter is only available if it also implements GAsyncInitable).

InputStream has functions to read from a stream (InputStreamExtManual::read()), to close a stream (InputStreamExt::close()) and to skip some content (InputStreamExt::skip()).

ListModel is an interface that represents a mutable list of GObjects. Its main intention is as a model for various widgets in user interfaces, such as list views, but it can also be used as a convenient method of returning lists of data, with support for updates.

ListStore is a simple implementation of ListModel that stores all items in memory.

A builder-pattern type to construct ListStore objects.

Extends the Icon interface and adds the ability to load icons from streams.

MemoryInputStream is a class for using arbitrary memory chunks as input for GIO streaming input operations.

MemoryMonitor will monitor system memory and suggest to the application when to free memory so as to leave more room for other applications. It is implemented on Linux using the Low Memory Monitor (API documentation).

MemoryOutputStream is a class for using arbitrary memory chunks as output for GIO streaming output operations.

Menu is a simple implementation of MenuModel. You populate a Menu by adding MenuItem instances to it.

MenuAttributeIter is an opaque structure type. You must access it using the functions below.

MenuItem is an opaque structure type. You must access it using the functions below.

MenuLinkIter is an opaque structure type. You must access it using the functions below.

MenuModel represents the contents of a menu – an ordered list of menu items. The items are associated with actions, which can be activated through them. Items can be grouped in sections, and may have submenus associated with them. Both items and sections usually have some representation data, such as labels or icons. The type of the associated action (ie whether it is stateful, and what kind of state it has) can influence the representation of the item.

The Mount interface represents user-visible mounts. Note, when porting from GnomeVFS, Mount is the moral equivalent of GnomeVFSVolume.

Flags used when mounting a mount.

MountOperation provides a mechanism for interacting with the user. It can be used for authenticating mountable operations, such as loop mounting files, hard drive partitions or server locations. It can also be used to ask the user questions or show a list of applications preventing unmount or eject operations from completing.

Flags used when an unmounting a mount.

NetworkAddress provides an easy way to resolve a hostname and then attempt to connect to that host, handling the possibility of multiple IP addresses and multiple address families.

NetworkMonitor provides an easy-to-use cross-platform API for monitoring network connectivity. On Linux, the available implementations are based on the kernel’s netlink interface and on NetworkManager.

Like NetworkAddress does with hostnames, NetworkService provides an easy way to resolve a SRV record, and then attempt to connect to one of the hosts that implements that service, handling service priority/weighting, multiple IP addresses, and multiple address families.

Notification is a mechanism for creating a notification to be shown to the user – typically as a pop-up notification presented by the desktop environment shell.

OutputStream has functions to write to a stream (OutputStreamExt::write()), to close a stream (OutputStreamExt::close()) and to flush pending writes (OutputStreamExt::flush()).

GOutputStreamSpliceFlags determine how streams should be spliced.

A Permission represents the status of the caller’s permission to perform a certain action.

PollableInputStream is implemented by GInputStreams that can be polled for readiness to read. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

PollableOutputStream is implemented by GOutputStreams that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

PowerProfileMonitor makes it possible for applications as well as OS components to monitor system power profiles and act upon them. It currently only exports whether the system is in “Power Saver” mode (known as “Low Power” mode on some systems).

A PropertyAction is a way to get a Action with a state value reflecting and controlling the value of a glib::Object property.

A Proxy handles connecting to a remote host via a given type of proxy server. It is implemented by the ‘gio-proxy’ extension point. The extensions are named after their proxy protocol name. As an example, a SOCKS5 proxy implementation can be retrieved with the name ‘socks5’ using the function g_io_extension_point_get_extension_by_name().

Support for proxied InetSocketAddress.

ProxyResolver provides synchronous and asynchronous network proxy resolution. ProxyResolver is used within SocketClient through the method SocketConnectableExt::proxy_enumerate().

The GRemoteActionGroup interface is implemented by ActionGroup instances that either transmit action invocations to other processes or receive action invocations in the local process from other processes.

Resolver provides cancellable synchronous and asynchronous DNS resolution, for hostnames (ResolverExt::lookup_by_address(), ResolverExt::lookup_by_name() and their async variants) and SRV (service) records (ResolverExt::lookup_service()).

Flags to modify lookup behavior.

Applications and libraries often contain binary or textual data that is really part of the application, rather than user data. For instance GtkBuilder .ui files, splashscreen images, GMenu markup XML, CSS files, icons, etc. These are often shipped as files in $datadir/appname, or manually included as literal strings in the code.

GResourceLookupFlags determine how resource path lookups are handled.

Seekable is implemented by streams (implementations of InputStream or OutputStream) that support seeking.

The Settings class provides a convenient API for storing and retrieving application settings.

The SettingsBackend interface defines a generic interface for non-strictly-typed data that is stored in a hierarchy. To implement an alternative storage backend for Settings, you need to implement the SettingsBackend interface and then make it implement the extension point SETTINGS_BACKEND_EXTENSION_POINT_NAME.

Flags used when creating a binding. These flags determine in which direction the binding works. The default is to synchronize in both directions.

The SettingsSchemaSource and SettingsSchema APIs provide a mechanism for advanced control over the loading of schemas and a mechanism for introspecting their content.

SettingsSchemaKey is an opaque data structure and can only be accessed using the following functions.

This is an opaque structure type. You may not access it directly.

A SimpleAction is the obvious simple implementation of the Action interface. This is the easiest way to create an action for purposes of adding it to a SimpleActionGroup.

SimpleActionGroup is a hash table filled with Action objects, implementing the ActionGroup and ActionMap interfaces.

GSimpleIOStream creates a IOStream from an arbitrary InputStream and OutputStream. This allows any pair of input and output streams to be used with IOStream methods.

SimplePermission is a trivial implementation of Permission that represents a permission that is either always or never allowed. The value is given at construction and doesn’t change.

A Socket is a low-level networking primitive. It is a more or less direct mapping of the BSD socket API in a portable GObject based API. It supports both the UNIX socket implementations and winsock2 on Windows.

SocketAddress is the equivalent of struct sockaddr in the BSD sockets API. This is an abstract class; use InetSocketAddress for internet sockets, or UnixSocketAddress for UNIX domain sockets.

SocketAddressEnumerator is an enumerator type for SocketAddress instances. It is returned by enumeration functions such as SocketConnectableExt::enumerate(), which returns a SocketAddressEnumerator to list each SocketAddress which could be used to connect to that SocketConnectable.

SocketClient is a lightweight high-level utility class for connecting to a network host using a connection oriented socket type.

Objects that describe one or more potential socket endpoints implement SocketConnectable. Callers can then use SocketConnectableExt::enumerate() to get a SocketAddressEnumerator to try out each socket address in turn until one succeeds, as shown in the sample code below.

SocketConnection is a IOStream for a connected socket. They can be created either by SocketClient when connecting to a host, or by SocketListener when accepting a new client.

A SocketListener is an object that keeps track of a set of server sockets and helps you accept sockets from any of the socket, either sync or async.

A SocketService is an object that represents a service that is provided to the network or over local sockets. When a new connection is made to the service the signal::SocketService::incoming signal is emitted.

SRV (service) records are used by some network protocols to provide service-specific aliasing and load-balancing. For example, XMPP (Jabber) uses SRV records to locate the XMPP server for a domain; rather than connecting directly to “example.com” or assuming a specific server hostname like “xmpp.example.com”, an XMPP client would look up the “xmpp-client” SRV record for “example.com”, and then connect to whatever host was pointed to by that record.

Subprocess allows the creation of and interaction with child processes.

Flags to define the behaviour of a Subprocess.

This class contains a set of options for launching child processes, such as where its standard input and output will be directed, the argument list, the environment, and more.

A Task represents and manages a cancellable “task”.

This is the subclass of SocketConnection that is created for TCP/IP sockets.

ThemedIcon is an implementation of Icon that supports icon themes. ThemedIcon contains a list of all of the icons present in an icon theme, so that icons can be looked up quickly. ThemedIcon does not provide actual pixmaps for icons, just the icon names. Ideally something like gtk_icon_theme_choose_icon() should be used to resolve the list of names so that fallback icons work nicely with themes that inherit other themes.

A ThreadedSocketService is a simple subclass of SocketService that handles incoming connections by creating a worker thread and dispatching the connection to it by emitting the signal::ThreadedSocketService::run signal in the new thread.

TLS (Transport Layer Security, aka SSL) and DTLS backend.

A certificate used for TLS authentication and encryption. This can represent either a certificate only (eg, the certificate received by a client from a server), or the combination of a certificate and a private key (which is needed when acting as a TlsServerConnection).

A set of flags describing TLS certification validation. This can be used to set which validation steps to perform (eg, with TlsClientConnectionExt::set_validation_flags()), or to describe why a particular certificate was rejected (eg, in signal::TlsConnection::accept-certificate).

TlsClientConnection is the client-side subclass of TlsConnection, representing a client-side TLS connection.

TlsConnection is the base TLS connection class type, which wraps a IOStream and provides TLS encryption on top of it. Its subclasses, TlsClientConnection and TlsServerConnection, implement client-side and server-side TLS, respectively.

TlsDatabase is used to look up certificates and other information from a certificate or key store. It is an abstract base class which TLS library specific subtypes override.

TlsFileDatabase is implemented by TlsDatabase objects which load their certificate information from a file. It is an interface which TLS library specific subtypes implement.

TlsInteraction provides a mechanism for the TLS connection and database code to interact with the user. It can be used to ask the user for passwords.

Holds a password used in TLS.

Various flags for the password.

TlsServerConnection is the server-side subclass of TlsConnection, representing a server-side TLS connection.

A UnixFDList contains a list of file descriptors. It owns the file descriptors that it contains, closing them when finalized.

UnixInputStream implements InputStream for reading from a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Defines a Unix mount entry (e.g. <filename>/media/cdrom</filename>). This corresponds roughly to a mtab entry.

Defines a Unix mount point (e.g. <filename>/dev</filename>). This corresponds roughly to a fstab entry.

UnixOutputStream implements OutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Support for UNIX-domain (also known as local) sockets.

Entry point for using GIO functionality.

The Volume interface represents user-visible objects that can be mounted. Note, when porting from GnomeVFS, Volume is the moral equivalent of GnomeVFSDrive.

Describes an event occurring on a SocketListener. See the signal::SocketListener::event signal for more details.

A protocol identifier is specified when creating a Socket, which is a family/type specific identifier, where 0 means the default protocol for the particular family/type.

Flags used when creating a Socket. Some protocols may not implement all the socket types.

The client authentication mode for a TlsServerConnection.

The type of TLS channel binding data to retrieve from TlsConnection or GDtlsConnection, as documented by RFC 5929. The tls-unique-for-telnet binding type is not currently implemented.

TlsInteractionResult is returned by various functions in TlsInteraction when finishing an interaction request.

The TLS or DTLS protocol version used by a TlsConnection or GDtlsConnection. The integer values of these versions are sequential to ensure newer known protocol versions compare greater than older known versions. Any known DTLS protocol version will compare greater than any SSL or TLS protocol version. The protocol version may be Unknown if the TLS backend supports a newer protocol version that GLib does not yet know about. This means that it’s possible for an unknown DTLS protocol version to compare less than the TLS protocol versions.

The type of name used by a UnixSocketAddress. Path indicates a traditional unix domain socket bound to a filesystem path. Anonymous indicates a socket not bound to any name (eg, a client-side socket, or a socket created with socketpair()).

Functions

Asynchronously connects to the message bus specified by bus_type.

Synchronously connects to the message bus specified by bus_type. Note that the returned object may shared with other callers, e.g. if two separate parts of a process calls this function with the same bus_type, they will share the same object.

Starts acquiring name on the bus specified by bus_type and calls name_acquired_handler and name_lost_handler when the name is acquired respectively lost. Callbacks will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this function from.

Like g_bus_own_name() but takes a DBusConnection instead of a BusType.

Stops owning a name.

Stops watching a name.

Starts watching name on the bus specified by bus_type and calls name_appeared_handler and name_vanished_handler when the name is known to have an owner respectively known to lose its owner. Callbacks will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this function from.

Like g_bus_watch_name() but takes a DBusConnection instead of a BusType.

Call from build script to run glib-compile-resources to generate compiled gresources to embed in binary with resources_register_include. target is relative to OUT_DIR.

Checks if a content type can be executable. Note that for instance things like text files can be executables (i.e. scripts and batch files).

Compares two content types for equality.

Tries to find a content type based on the mime type name.

Gets the human readable description of the content type.

Gets the generic icon name for a content type.

Gets the icon for a content type.

Get the list of directories which MIME data is loaded from. See content_type_set_mime_dirs() for details.

Gets the mime type for the content type, if one is registered.

Gets the symbolic icon for a content type.

Guesses the content type based on example data. If the function is uncertain, result_uncertain will be set to true. Either filename or data may be None, in which case the guess will be based solely on the other argument.

Tries to guess the type of the tree with root root, by looking at the files it contains. The result is an array of content types, with the best guess coming first.

Determines if type_ is a subset of supertype.

Determines if type_ is a subset of mime_type. Convenience wrapper around content_type_is_a().

Checks if the content type is the generic “unknown” type. On UNIX this is the “application/octet-stream” mimetype, while on win32 it is “*” and on OSX it is a dynamic type or octet-stream.

Set the list of directories used by GIO to load the MIME database. If dirs is None, the directories used are the default:

Gets a list of strings containing all the registered content types known to the system. The list and its data should be freed using g_list_free_full (list, g_free).

Escape string so it can appear in a D-Bus address as the value part of a key-value pair.

Synchronously looks up the D-Bus address for the well-known message bus instance specified by bus_type. This may involve using various platform specific mechanisms.

Asynchronously connects to an endpoint specified by address and sets up the connection so it is in a state to run the client-side of the D-Bus authentication conversation. address must be in the D-Bus address format.

Synchronously connects to an endpoint specified by address and sets up the connection so it is in a state to run the client-side of the D-Bus authentication conversation. address must be in the D-Bus address format.

This is a language binding friendly version of g_dbus_escape_object_path_bytestring().

Generate a D-Bus GUID that can be used with e.g. DBusConnection::new().

Converts a glib::Value to a glib::Variant of the type indicated by the type_ parameter.

Converts a glib::Variant to a glib::Value. If value is floating, it is consumed.

Checks if string is a D-Bus address.

Check whether string is a valid D-Bus error name.

Checks if string is a D-Bus GUID.

Checks if string is a valid D-Bus interface name.

Checks if string is a valid D-Bus member (e.g. signal or method) name.

Checks if string is a valid D-Bus bus name (either unique or well-known).

Like dbus_is_address() but also checks if the library supports the transports in string and that key/value pairs for each transport are valid. See the specification of the D-Bus address format.

Checks if string is a valid D-Bus unique bus name.

Converts errno.h error codes into GIO error codes. The fallback value IOErrorEnum::Failed is returned for error codes not currently handled (but note that future GLib releases may return a more specific value instead).

Scans all the modules in the specified directory, ensuring that any extension point implemented by a module is registered.

Cancels all cancellable I/O jobs.

Initializes the platform networking libraries (eg, on Windows, this calls WSAStartup()). GLib will call this itself if it is needed, so you only need to call it if you directly call system networking functions (without calling any GLib networking functions first).

Returns all the names of children at the specified path in the set of globally registered resources. The return result is a None terminated list of strings which should be released with g_strfreev().

Looks for a file at the specified path in the set of globally registered resources and if found returns information about it.

Looks for a file at the specified path in the set of globally registered resources and returns a glib::Bytes that lets you directly access the data in memory.

Looks for a file at the specified path in the set of globally registered resources and returns a InputStream that lets you read the data.

Registers the resource with the process-global set of resources. Once a resource is registered the files in it can be accessed with the global resource lookup functions like resources_lookup_data().

Unregisters the resource from the process-global set of resources.

Determines if mount_path is considered an implementation of the OS. This is primarily used for hiding mountable and mounted volumes that only are used in the OS and has little to no relevance to the casual user.

Determines if device_path is considered a block device path which is only used in implementation of the OS. This is primarily used for hiding mounted volumes that are intended as APIs for programs to read, and system administrators at a shell; rather than something that should, for example, appear in a GUI. For example, the Linux /proc filesystem.

Determines if fs_type is considered a type of file system which is only used in implementation of the OS. This is primarily used for hiding mounted volumes that are intended as APIs for programs to read, and system administrators at a shell; rather than something that should, for example, appear in a GUI. For example, the Linux /proc filesystem.
