Struct TypedState 

pub struct TypedState<T, const N: usize> { /* private fields */ }

Retained independent channel trajectories. No allocation occurs in sampling.

Implementations

impl<T: MotionData<N>, const N: usize> TypedState<T, N>

pub fn new(value: T) -> Self

Seeds all channels. Panics for a non-finite seed or an empty representation.

pub fn sample( &mut self, clip: &TypedAnimation<T, N>, now: Duration, reduced: bool, ) -> TypedFrame<T>

Samples at one explicit monotonic epoch. Panics if the clip’s mask differs from the seed’s mask; create a new retained state for a different shape.

pub fn value(&self) -> T

Last sampled value.

pub fn velocities(&self) -> [f64; N]

Per-channel physical velocity.

pub fn pause(&mut self, now: Duration)

Pauses every channel.

pub fn play(&mut self, now: Duration)

Resumes every channel.

pub fn seek(&mut self, time: Duration, now: Duration)

Seeks every channel.

pub fn restart(&mut self, now: Duration)

Restarts every channel; cancels previous completion observers.

pub fn set_speed( &mut self, speed: f64, now: Duration, ) -> Result<(), AnimationError>

Validates and changes speed for all channels transactionally.

pub fn finish(&mut self)

Completes all channels at the next sample, including forever clips.

pub fn completion(&mut self) -> Completion

Observes completion/cancellation. All channels share the same clip timing.

pub fn is_animating(&self) -> bool

Whether the last sample requires another frame.

pub fn now(&self, cx: &App) -> Duration

Native executor time for controls; zero before the first native frame.

pub fn frame( &mut self, clip: &TypedAnimation<T, N>, window: &mut Window, cx: &App, ) -> TypedFrame<T>

Samples on stock CE and schedules only while active. Do not mix clocks.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
