Struct gio::Volume

source ·
#[repr(transparent)]
pub struct Volume { /* private fields */ }
Expand description

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

Mounting a Volume instance is an asynchronous operation. For more information about asynchronous operations, see AsyncResult and Task. To mount a Volume, first call VolumeExt::mount() with (at least) the Volume instance, optionally a MountOperation object and a GAsyncReadyCallback.

Typically, one will only want to pass None for the MountOperation if automounting all volumes when a desktop session starts since it’s not desirable to put up a lot of dialogs asking for credentials.

The callback will be fired when the operation has resolved (either with success or failure), and a AsyncResult instance will be passed to the callback. That callback should then call g_volume_mount_finish() with the Volume instance and the AsyncResult data to see if the operation was completed successfully. If an error is present when g_volume_mount_finish() is called, then it will be filled with any error information.

Volume Identifiers # {volume-identifier}

It is sometimes necessary to directly access the underlying operating system object behind a volume (e.g. for passing a volume to an application via the commandline). For this purpose, GIO allows to obtain an ‘identifier’ for the volume. There can be different kinds of identifiers, such as Hal UDIs, filesystem labels, traditional Unix devices (e.g. /dev/sda2), UUIDs. GIO uses predefined strings as names for the different kinds of identifiers: VOLUME_IDENTIFIER_KIND_UUID, VOLUME_IDENTIFIER_KIND_LABEL, etc. Use VolumeExt::identifier() to obtain an identifier for a volume.

Note that VOLUME_IDENTIFIER_KIND_HAL_UDI will only be available when the gvfs hal volume monitor is in use. Other volume monitors will generally be able to provide the VOLUME_IDENTIFIER_KIND_UNIX_DEVICE identifier, which can be used to obtain a hal device by means of libhal_manager_find_device_string_match().
