Enum Easing 

pub enum Easing {
    Linear,
    EaseIn,
    EaseOut,
    EaseInOut,
    CubicBezier(f32, f32, f32, f32),
}

Easing curve sampled by Easing::apply. The curves match common CSS / native-control timings:

• Linear - uniform speed; not common in UI but useful for tests.
• EaseIn - cubic ease-in (slow start).
• EaseOut - cubic ease-out (fast start, slow settle); matches the Cocoa AppKit / Material 3 short-transition curve.
• EaseInOut - cubic ease-in-out.
• CubicBezier(p1x, p1y, p2x, p2y) - CSS cubic-bezier(...) form.

Variants

Linear

f(t) = t.

EaseIn

f(t) = t^3.

EaseOut

f(t) = 1 - (1 - t)^3.

EaseInOut

f(t) = 0.5*(2t)^3 for t < 0.5, mirrored above.

CubicBezier(f32, f32, f32, f32)

CSS cubic-bezier(p1x, p1y, p2x, p2y). Anchors are implicit (0, 0) and (1, 1).

Implementations

impl Easing

pub fn apply(self, t: f32) -> f32

Map a linear progress t in [0, 1] through the curve.

Trait Implementations

impl Clone for Easing

fn clone(&self) -> Easing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Easing

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

Formats the value using the given formatter.

impl PartialEq for Easing

fn eq(&self, other: &Easing) -> 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.

impl Copy for Easing
