Enum Easing 

pub enum Easing {
    Linear,
    EaseIn,
    EaseOut,
    EaseInOut,
    CubicBezier {
        x1: f32,
        y1: f32,
        x2: f32,
        y2: f32,
    },
}

A timing function mapping linear progress t ∈ [0, 1] to eased progress.

Variants

Linear

Identity: output equals input.

EaseIn

Slow start (cubic-bezier(0.42, 0, 1, 1)).

EaseOut

Slow end (cubic-bezier(0, 0, 0.58, 1)).

EaseInOut

Slow start and end (cubic-bezier(0.42, 0, 0.58, 1)).

CubicBezier

An arbitrary cubic Bézier with control points (x1, y1) and (x2, y2); endpoints are fixed at (0,0) and (1,1) as in CSS.

Fields

x1: f32

First control-point x.

y1: f32

First control-point y.

x2: f32

Second control-point x.

y2: f32

Second control-point y.

Implementations

impl Easing

pub fn eval(&self, t: f32) -> f32
