Enum Ease 

pub enum Ease {
    Linear,
    Hold,
    Ease,
    In,
    Out,
    InOut,
    Back,
    Smoothstep,
    Bezier([f64; 4]),
}

The shape of a move over its progress u (0..1): a key’s interp (alias ease).

Variants

Linear

Hold

Keeps this key’s value until the next key.

Ease

0.5 - 0.5 cos(pi u) (reframe’s ease).

In

Cubic, accelerating.

Out

Cubic, decelerating.

InOut

Cubic ease in and out.

Back

Decelerates past the end and settles back (overshoot).

Smoothstep

3u² − 2u³ (the audio schemas’ ease).

Bezier([f64; 4])

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

Implementations

impl Ease

pub fn from_name(s: &str) -> Option<Self>

A name: linear, hold, ease, in, out, in_out, back, smoothstep (and the aliases ease_in, ease_out, ease_in_out, overshoot).

pub fn parse(v: &Value) -> Option<Self>

A name or [x1, y1, x2, y2] (x1 and x2 in 0..1, as in CSS).

pub fn at(self, u: f64) -> f64

Progress at u, clamped to 0..1 (Back overshoots 1 on the way).
