Module animation 

Clock-free easing and value interpolation.

Structs

Constant

An unbounded constant signal.

Delay

A delayed animation produced by FiniteAnimation::delay.

FollowPath

Finite path motion sampled by normalized arc length.

Interval

A half-open interval [start, start + duration) on a timeline.

Keyframes

A nonempty track starting at zero, with absolute destinations and relative holds.

Map

Value mapping produced by Signal::map.

Noise

Infinite deterministic multi-octave noise animation in minus one to one.

NoiseBuilder

Unvalidated noise configuration; NoiseBuilder::build reports invalid values.

Oscillator

Infinite stateless periodic scalar animation.

OscillatorBuilder

Unvalidated oscillator configuration; OscillatorBuilder::build reports invalid values.

PathSample

One arc-length path sample in local geometry coordinates.

PingPong

A finite forward/backward cycle produced by FiniteAnimation::ping_pong.

Repeat

A finite repetition produced by FiniteAnimation::repeat.

Reverse

A reversed finite animation produced by FiniteAnimation::reverse.

Speed

A time-scaled animation produced by FiniteAnimation::speed.

Spring

A finite physical spring between arbitrary interpolatable values.

SpringBuilder

Unvalidated spring configuration; SpringBuilder::build reports invalid parameters.

Then

A finite sequence produced by FiniteAnimation::then.

Tween

A finite endpoint-to-endpoint interpolation with double-precision progress.

Zip

Parallel sampling produced by Signal::zip.

Enums

Easing

A normalized double-precision easing curve, independent of clip duration.

Extrapolate

Behavior outside a mapping’s input interval.

Waveform

Periodic waveform evaluated in turns.

Traits

FiniteAnimation

A Signal with a nonnegative, stable duration.

Interpolate

Values that can interpolate between endpoints. Progress may overshoot 0.0..=1.0. Implement this trait to sample custom values with Tween and Keyframes. Progress and geometry use double precision. f32 values retain their own arithmetic; colors extrapolate Oklab and clamp only alpha.

Signal

A thread-safe, randomly addressable signal of values over signed local time.

Functions

piecewise

Interpolates matching samples with finite strictly increasing input knots.

remap

Maps one finite scalar interval; reversed endpoints are supported.

try_piecewise

Interpolates like piecewise, reporting invalid knots, easing and mapping errors.

try_remap

Maps like remap, reporting nonfinite inputs, equal input endpoints and overflow.

try_value_noise

Evaluates value_noise, reporting a nonfinite position.

value_noise

One-dimensional slice of crate::noise::value2_d along y = 0, with its derivative.
