Struct Parallel 

pub struct Parallel<T: Animatable> { /* private fields */ }

Runs child animations together and composes their output values.

Implementations

impl<T: Animatable> Parallel<T>

pub fn new(initial: T, compose: impl Fn(&[T]) -> T + 'static) -> Self

Creates an empty parallel animation with an output compositor.

pub fn with(self, animation: impl Animation<T>) -> Self

Appends an animation and returns the updated parallel composition.

pub fn push(&mut self, animation: impl Animation<T>)

Appends an animation to the parallel composition.

pub fn len(&self) -> usize

Returns the number of child animations.

pub fn is_empty(&self) -> bool

Returns whether the composition contains no child animations.

Trait Implementations

impl<T: Animatable> Animation<T> for Parallel<T>

fn value(&self) -> &T

Returns the animation’s current value.

fn state(&self) -> AnimationState

Returns the animation’s lifecycle state.

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

Returns the total duration when it is finite and known.

fn tick(&mut self, delta: Duration)

Advances the animation by delta.

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

Advances the animation and returns any unconsumed duration.

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.

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

Attempts to continue the animation toward a new target.

fn is_active(&self) -> bool

Returns whether the animation is currently running.
