#[repr(transparent)]pub struct FileInfo { /* private fields */ }
Expand description
Functionality for manipulating basic metadata for files. FileInfo
implements methods for getting information that all files should
contain, and allows for manipulation of extended attributes.
See [GFileAttribute][gio-GFileAttribute] for more information on how GIO handles file attributes.
To obtain a FileInfo
for a File
, use FileExt::query_info()
(or its
async variant). To obtain a FileInfo
for a file input or output
stream, use FileInputStreamExt::query_info()
or
FileOutputStreamExt::query_info()
(or their async variants).
To change the actual attributes of a file, you should then set the
attribute in the FileInfo
and call FileExt::set_attributes_from_info()
or FileExt::set_attributes_async()
on a GFile.
However, not all attributes can be changed in the file. For instance,
the actual size of a file cannot be changed via set_size()
.
You may call FileExt::query_settable_attributes()
and
FileExt::query_writable_namespaces()
to discover the settable attributes
of a particular file at runtime.
The direct accessors, such as name()
, are slightly more
optimized than the generic attribute accessors, such as
attribute_byte_string()
.This optimization will matter
only if calling the API in a tight loop.
FileAttributeMatcher
allows for searching through a FileInfo
for
attributes.
