Struct MotionScalarController 

pub struct MotionScalarController<K> { /* private fields */ }

A small keyed scalar motion controller.

Implementations

impl<K> MotionScalarController<K>

pub const fn new() -> Self

Creates an empty scalar motion controller.

pub fn tracks(&self) -> &[(K, MotionScalarTrack)]

Returns all registered tracks in insertion order.

impl<K: PartialEq> MotionScalarController<K>

pub fn start( &mut self, key: K, model: MotionModel, from: f32, target: f32, initial_velocity: f32, started_at: Duration, )

Starts or replaces a keyed scalar track.

pub fn set_immediate(&mut self, key: K, value: f32, now: Duration)

Sets or replaces a keyed scalar track with an immediate fixed value.

pub fn retarget( &mut self, key: K, model: MotionModel, target: f32, now: Duration, )

Retargets an existing keyed track from its sampled value and velocity.

pub fn cancel(&mut self, key: &K, now: Duration)

Cancels an existing keyed track at the provided controller time.

pub fn finish(&mut self, key: &K, now: Duration)

Finishes an existing keyed track at the provided controller time.

pub fn frame_demand_at(&self, now: Duration) -> MotionFrameDemand

Returns the frame demand at the provided controller time.

impl<K> MotionScalarController<K>

pub fn prune_terminal_at(&mut self, now: Duration) -> usize

Removes terminal tracks and returns the number of pruned entries.

impl<K: Clone> MotionScalarController<K>

pub fn sample_at(&self, now: Duration) -> MotionScalarControllerSample<K>

Samples all tracks at the provided controller time.

pub fn sample_clock( &self, clock: MotionClockSample, ) -> MotionScalarControllerSample<K>

Samples all tracks at a deterministic adapter clock sample.

pub fn sample_since( &self, started_at: Instant, now: Instant, ) -> MotionScalarControllerSample<K>

Samples all tracks from adapter instants while keeping deterministic elapsed-time semantics in the controller layer.
