/**
 * GVolumeIface:
 * @g_iface: The parent interface.
 * @changed: Changed signal that is emitted when the volume's state has changed.
 * @removed: The removed signal that is emitted when the #GVolume have been removed. If the recipient is holding references to the object they should release them so the object can be finalized.
 * @get_name: Gets a string containing the name of the #GVolume.
 * @get_icon: Gets a #GIcon for the #GVolume.
 * @get_uuid: Gets the UUID for the #GVolume. The reference is typically based on the file system UUID for the mount in question and should be considered an opaque string. Returns %NULL if there is no UUID available.
 * @get_drive: Gets a #GDrive the volume is located on. Returns %NULL if the #GVolume is not associated with a #GDrive.
 * @get_mount: Gets a #GMount representing the mounted volume. Returns %NULL if the #GVolume is not mounted.
 * @can_mount: Returns %TRUE if the #GVolume can be mounted.
 * @can_eject: Checks if a #GVolume can be ejected.
 * @mount_fn: Mounts a given #GVolume. 
 *     #GVolume implementations must emit the #GMountOperation::aborted 
 *     signal before completing a mount operation that is aborted while 
 *     awaiting input from the user through a #GMountOperation instance.
 * @mount_finish: Finishes a mount operation.
 * @eject: Ejects a given #GVolume.
 * @eject_finish: Finishes an eject operation.
 * @get_identifier: Returns the <link linkend="volume-identifier">identifier</link> of the given kind, or %NULL if
 *    the #GVolume doesn't have one.
 * @enumerate_identifiers: Returns an array strings listing the kinds
 *    of <link linkend="volume-identifier">identifiers</link> which the #GVolume has.
 * @should_automount: Returns %TRUE if the #GVolume should be automatically mounted.
 * @get_activation_root: Returns the activation root for the #GVolume if it is known in advance or %NULL if
 *   it is not known.
 * @eject_with_operation: Starts ejecting a #GVolume using a #GMountOperation. Since 2.22.
 * @eject_with_operation_finish: Finishes an eject operation using a #GMountOperation. Since 2.22.
 *
 * Interface for implementing operations for mountable volumes.
