Trait polyhorn_ui::animation::AnimationHandle

pub trait AnimationHandle: Future<Output = ()> + Send + Sync { }

Trait that should be implemented by animation handles that are returned by the animator trait's start function. This handle can be used to wait for an animation to complete (because it is a future) or cancel a pending animation by dropping it.

Note: the handle itself doesn't necessarily have to implement Drop, it might have a field that holds an internal representation that implements Drop. For example, on iOS the AnimationHandle has a field that holds a reference counted PLYAnimationHandle that is written in Objective-C. Once the reference count drops to zero and the Objective-C object is released, it will automatically remove the animation from its view.
