Struct Easing 

pub struct Easing { /* private fields */ }

A cubic-bezier easing from (0, 0) to (1, 1) through two control points. The x coordinates are clamped to 0..=1 (so time only moves forward) and the y coordinates to −1..=2.

Implementations

impl Easing

pub const LINEAR: Easing

Constant speed.

pub const EASE: Easing

CSS ease.

pub const EASE_IN: Easing

CSS ease-in.

pub const EASE_OUT: Easing

CSS ease-out.

pub const EASE_IN_OUT: Easing

CSS ease-in-out.

pub const fn cubic_bezier(x1: f32, y1: f32, x2: f32, y2: f32) -> Easing

cubic-bezier(x1, y1, x2, y2). NaN coordinates take the linear curve’s; others are clamped.

pub const fn points(self) -> [f32; 4]

The control points [x1, y1, x2, y2].

pub fn ease(self, u: f32) -> f32

Progress at time fraction u (clamped to 0..=1; NaN is 0).

pub fn slope(self, u: f32) -> f32

The slope d(progress)/d(time fraction) at u (clamped to 0..=1), bounded to ±10⁴.

impl Copy for Easing

impl Debug for Easing

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