#[repr(transparent)]pub struct Device { /* private fields */ }Expand description
Device are objects representing a device, they contain
relevant metadata about the device, such as its class and the Caps
representing the media types it can produce or handle.
Device are created by DeviceProvider objects which can be
aggregated by DeviceMonitor objects.
This is an Abstract Base Class, you cannot instantiate it.

parent
The parent of the object. Please note, that when changing the ‘parent’
property, we don’t emit notify and deep-notify
signals due to locking issues. In some cases one can use
element-added or element-removed signals on the parent to
achieve a similar effect.

deep-notify
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.
