Module anim 

Animation primitives: tweens, springs, keyframes, sequences, and staggers.

All animations are tick-based — call the value() method each frame with the current Context::tick to advance. No timers or threads involved.

Structs

Keyframes

Multi-stop keyframe animation over a fixed tick duration.

Sequence

Sequential timeline that chains multiple animation segments.

Spring

Spring physics animation that settles toward a target value.

Stagger

Parallel staggered animation where each item starts after a fixed delay.

Tween

Linear interpolation between two values over a duration, with optional easing.

Enums

LoopMode

Defines how an animation behaves after reaching its end.

Functions

ease_in_cubic

Cubic ease-in: slow start, fast end (stronger than quadratic).

ease_in_out_cubic

Cubic ease-in-out: slow start, fast middle, slow end (stronger than quadratic).

ease_in_out_quad

Quadratic ease-in-out: slow start, fast middle, slow end.

ease_in_quad

Quadratic ease-in: slow start, fast end.

ease_linear

Linear easing: constant rate from 0.0 to 1.0.

ease_out_bounce

Bounce ease-out: simulates a ball bouncing before coming to rest.

ease_out_cubic

Cubic ease-out: fast start, slow end (stronger than quadratic).

ease_out_elastic

Elastic ease-out: overshoots the target and oscillates before settling.

ease_out_quad

Quadratic ease-out: fast start, slow end.

lerp

Linear interpolation between a and b at position t (0.0..=1.0).
