Enum RateFn 

pub enum RateFn {
    Linear,
    Smooth,
    ThereAndBack,
    EaseIn(Ease),
    EaseOut(Ease),
    EaseInOut(Ease),
    Spring {
        stiffness: f32,
        damping: f32,
    },
    Custom(fn(f32) -> f32),
}

Maps linear progress 0..=1 to eased progress.

Variants

Linear

No easing.

Smooth

Smootherstep; close to manim’s default smooth.

ThereAndBack

Smooth out to 1 at the midpoint and back to 0.

EaseIn(Ease)

Starts slow.

EaseOut(Ease)

Ends slow.

EaseInOut(Ease)

Starts and ends slow.

Spring

Damped oscillation that overshoots and settles at 1: stiffness is the angular frequency and damping the decay rate, both per clip (e.g. 20 and 6).

Fields

stiffness: f32

Angular frequency in radians per clip.

damping: f32

Exponential decay rate per clip.

Custom(fn(f32) -> f32)

Any function with f(0) == 0.

Implementations

impl RateFn

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