Struct BezierEasing 

#[repr(C)]
pub struct BezierEasing {
    pub x1: f32,
    pub y1: f32,
    pub x2: f32,
    pub y2: f32,
}

Cubic Bezier easing with two control points.

The curve starts at (0, 0) and ends at (1, 1). The control points (x1, y1) and (x2, y2) shape the curve between those endpoints.

Fields

x1: f32

X coordinate of the first control point.

y1: f32

Y coordinate of the first control point.

x2: f32

X coordinate of the second control point.

y2: f32

Y coordinate of the second control point.

Implementations

impl BezierEasing

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

Creates a new cubic Bezier easing curve.

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

Evaluates the easing curve at time t in [0, 1].

Uses Newton’s method to find the parameter on the Bezier curve whose X coordinate matches t, then returns the corresponding Y.

Trait Implementations

impl Clone for BezierEasing

fn clone(&self) -> BezierEasing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BezierEasing

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

Formats the value using the given formatter.

impl PartialEq for BezierEasing

fn eq(&self, other: &BezierEasing) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
