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.

It is an error to call these accessors without specifying their required file attributes when creating the FileInfo. Use has_attribute() or list_attributes() to check what attributes are specified for a FileInfo.

FileAttributeMatcher allows for searching through a FileInfo for attributes.
