fn id(&self) -> GString
Gets the

of some associated asset. It may be the case
that the object has no set asset, or even that such an asset does not
yet exist in the GES cache. Instead, this will return the asset
id
that is compatible with the current state of the object,
as determined by the Extractable
implementer. If it was indeed
extracted from an asset, this should return the same as its
corresponding asset id

fn child_property(&self, property_name: &str) -> Option<Value>
In general, a copy is made of the property contents and
the caller is responsible for freeing the memory by calling

fn control_binding(&self, property_name: &str) -> Option<ControlBinding>
Gets the control binding that was created for the specified child
property of the track element using

fn lookup_child(&self, prop_name: &str) -> Option<(Element, ParamSpec)>
Looks up which
