Fields

image: OnceCell<Arc<Image<'static>>>

The source image.

current_frame: RefCell<Option<Frame>>

The current frame that is displayed.

next_frame: RefCell<Option<Frame>>

The next frame of the animation, if any.

timeout_source_id: RefCell<Option<SourceId>>

The source ID of the timeout to load the next frame, if any.

animation_ref: OnceCell<CountedRef>

The counted reference for the animation.

When the count is 0, the animation is paused.
