Trait Implementations

impl IAnimationInstance for ExpressionAnimationInstance

fn target_object(&self) -> ServerObjectId

The object whose property is animated.

fn resolve(&self, compositor: &Rc<ServerCompositor>)

Resolves the server objects the instance refers to by id, on the compositor that drives it. Called once, on the server, before the instance is initialized; an instance that refers to no object needs nothing.

fn evaluate( &self, now: Duration, current_value: ExpressionVariant, ) -> ExpressionVariant

The value of the animation at now.

fn initialize( &self, _started_at: Duration, starting_value: ExpressionVariant, property: &'static CompositionProperty, )

Attaches the instance to the property it animates.

fn activate(&self)

fn deactivate(&self)

fn invalidate(&self)

impl IServerClockItem for ExpressionAnimationInstance

fn on_tick(&self)
