Struct Fade 

pub struct Fade { /* private fields */ }

Linear progression from 0.0 to 1.0 over a duration, with configurable easing.

Tracks elapsed time as Duration internally for precise accumulation (no floating-point drift) and accurate overshoot calculation.

Implementations

impl Fade

pub fn new(duration: Duration) -> Self

Create a fade with the given duration and default linear easing.

pub fn easing(self, easing: EasingFn) -> Self

Set the easing function.

pub fn raw_progress(&self) -> f32

Raw linear progress (before easing), in [0.0, 1.0].

Trait Implementations

impl Animation for Fade

fn tick(&mut self, dt: Duration)

Advance the animation by dt.

fn is_complete(&self) -> bool

Whether the animation has reached its end.

fn value(&self) -> f32

Current output value, clamped to [0.0, 1.0].

fn reset(&mut self)

Reset the animation to its initial state.

fn overshoot(&self) -> Duration

Time elapsed past completion. Used by composition types to forward remaining time (e.g., Sequence forwards overshoot from first to second). Returns Duration::ZERO for animations that never complete.

impl Clone for Fade

fn clone(&self) -> Fade

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fade

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Copy for Fade
