Struct Tween 

pub struct Tween<T> { /* private fields */ }

Animates a Signal towards a target. Created by Signal::to.

The first poll captures the start value and the task time; every later poll is one frame. On completion the task time is advanced to exactly start + duration, not to the frame time, so chained tweens do not accumulate rounding drift.

Implementations

impl<T: Lerp + Clone + 'static> Tween<T>

pub fn ease(self, ease: impl Ease + 'static) -> Self

Easing curve of this tween; default presets::DEFAULT.

pub fn duration(self, duration: impl Seconds) -> Self

Changes the length, e.g. of a helper like fade_in() that defaults to the theme’s pace: title.fade_in().duration(0.3).

pub fn from(self, value: T) -> Self

Starts from value instead of the signal’s value at the first poll.

Trait Implementations

impl<T: Lerp + Clone + Unpin + 'static> Future for Tween<T>

type Output = ()

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<()>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
