Struct CubicBezier 

pub struct CubicBezier {
    pub x1: f32,
    pub y1: f32,
    pub x2: f32,
    pub y2: f32,
}

A CSS cubic-bezier(x1, y1, x2, y2) timing curve.

x1 and x2 lie in 0..=1, which keeps the curve a function of its input. y1 and y2 are unbounded: a curve may overshoot and come back.

Fields

x1: f32

Horizontal coordinate of the first control point, in 0..=1.

y1: f32

Vertical coordinate of the first control point.

x2: f32

Horizontal coordinate of the second control point, in 0..=1.

y2: f32

Vertical coordinate of the second control point.

Implementations

impl CubicBezier

pub const fn new(x1: f32, y1: f32, x2: f32, y2: f32) -> Self

Creates a curve from its two inner control points.

pub fn is_valid(self) -> bool

Whether every coordinate is finite and x1, x2 lie in 0..=1.

pub fn apply(self, progress: f64) -> f64

The curve’s output at linear progress, which is clamped to 0..=1.

The ends are exact: 0 maps to 0 and 1 to 1. Between them the output may leave 0..=1 when y1 or y2 does.
