Struct AnimatedValue 

pub struct AnimatedValue<T: Interpolate + Clone> { /* private fields */ }

Animated value that transitions smoothly.

Supports two modes:

• Tween (when spec.spring is None): interpolates between start and target over a fixed duration using an easing curve.
• Spring (when spec.spring is Some): numerically integrates a physical spring ODE (x'' = -k·(x - target) - d·x') with emergent duration. When the target changes mid-animation, the current value and velocity carry forward seamlessly.

Implementations

impl AnimatedValue<f32>

pub fn update_decay(&mut self, friction: f32, stop_threshold: f32) -> bool

Tick the decay animation. Returns true if still animating.

impl<T: Interpolate + Clone> AnimatedValue<T>

pub fn new(initial: T, spec: AnimationSpec) -> Self

pub fn set_spec(&mut self, spec: AnimationSpec)

pub fn set_keyframes(&mut self, keyframes: KeyframesSpec<T>)

Set a keyframes spec for multi-stage animation. When set, set_target is ignored and the value is driven by the keyframe sequence.

pub fn set_target(&mut self, target: T)

pub fn snap_to(&mut self, value: T)

Snap immediately to a value without animating.

pub fn update(&mut self) -> bool

pub fn get(&self) -> &T

pub fn is_animating(&self) -> bool

pub fn has_keyframes(&self) -> bool
