/**
* 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 [identifier][volume-identifier] of the given kind, or %NULL if
* the #GVolume doesn't have one.
* @enumerate_identifiers: Returns an array strings listing the kinds
* of [identifiers][volume-identifier] 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.
* @get_sort_key: Gets a key used for sorting #GVolume instance or %NULL if no such key exists. Since 2.32.
* @get_symbolic_icon: Gets a symbolic #GIcon for the #GVolume. Since 2.34.
*
* Interface for implementing operations for mountable volumes.
