/// `GDrive` represents a piece of hardware connected to the machine.
/// It’s generally only created for removable hardware or hardware with
/// removable media. For example, an optical disc drive, or a USB flash drive.
///
/// `GDrive` is a container class for [`Volume`][crate::Volume] objects that stem from
/// the same piece of media. As such, `GDrive` abstracts a drive with
/// (or without) removable media and provides operations for querying
/// whether media is available, determining whether media change is
/// automatically detected and ejecting the media.
///
/// If the `GDrive` reports that media isn’t automatically detected, one
/// can poll for media; typically one should not do this periodically
/// as a poll for media operation is potentially expensive and may
/// spin up the drive creating noise.
///
/// `GDrive` supports starting and stopping drives with authentication
/// support for the former. This can be used to support a diverse set
/// of use cases including connecting/disconnecting iSCSI devices,
/// powering down external disk enclosures and starting/stopping
/// multi-disk devices such as RAID devices. Note that the actual
/// semantics and side-effects of starting/stopping a `GDrive` may vary
/// according to implementation. To choose the correct verbs in e.g. a
/// file manager, use [`DriveExt::start_stop_type()`][crate::prelude::DriveExt::start_stop_type()].
///
/// For [porting from GnomeVFS](migrating-gnome-vfs.html) note that there is no
/// equivalent of `GDrive` in that API.
///
/// ## Signals
///
///
/// #### `changed`
/// Emitted when the drive's state has changed.
///
///
///
///
/// #### `disconnected`
/// This signal is emitted when the #GDrive have been
/// disconnected. If the recipient is holding references to the
/// object they should release them so the object can be
/// finalized.
///
///
///
///
/// #### `eject-button`
/// Emitted when the physical eject button (if any) of a drive has
/// been pressed.
///
///
///
///
/// #### `stop-button`
/// Emitted when the physical stop button (if any) of a drive has
/// been pressed.
