A stateful source that produces animated values over time.

Required Methods

fn value(&self) -> &T

Returns the animation’s current value.

fn state(&self) -> AnimationState

Returns the animation’s lifecycle state.

fn tick(&mut self, delta: Duration)

Advances the animation by delta.

fn pause(&mut self)

Pauses a running animation.

fn resume(&mut self)

Resumes a paused animation.

fn cancel(&mut self)

Cancels the animation.

fn seek(&mut self, progress: f32)

Seeks to normalized progress within the animation.

fn finish(&mut self)

Moves the animation to its completed state.

Provided Methods

fn duration(&self) -> Option<Duration>

Returns the total duration when it is finite and known.

fn advance(&mut self, delta: Duration) -> Duration

Advances the animation and returns any unconsumed duration.

fn retarget(&mut self, _target: &T) -> bool

Attempts to continue the animation toward a new target.

Returns true when the animation supports retargeting.

fn is_active(&self) -> bool

Returns whether the animation is currently running.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
