Struct MotionScalarTrack 

pub struct MotionScalarTrack { /* private fields */ }

One scalar motion track sampled by deterministic elapsed time.

Implementations

impl MotionScalarTrack

pub fn start( model: MotionModel, from: f32, target: f32, initial_velocity: f32, started_at: Duration, ) -> Self

Starts a scalar track at the provided controller time.

pub fn immediate(value: f32, started_at: Duration) -> Self

Creates an immediate scalar track at a fixed value.

pub const fn model(&self) -> MotionModel

Returns the motion model.

pub const fn from(&self) -> f32

Returns the source value.

pub const fn target(&self) -> f32

Returns the target value.

pub const fn initial_velocity(&self) -> f32

Returns the initial velocity.

pub const fn started_at(&self) -> Duration

Returns the controller time at which the track started.

pub const fn cancelled_at(&self) -> Option<Duration>

Returns the controller time at which the track was cancelled.

pub const fn finished_at(&self) -> Option<Duration>

Returns the controller time at which the track was explicitly finished.

pub fn cancel_at(&mut self, cancelled_at: Duration)

Cancels the track at the provided controller time.

pub fn finish_at(&mut self, finished_at: Duration)

Finishes the track at the provided controller time and publishes the target value.

pub fn retarget(&self, model: MotionModel, target: f32, now: Duration) -> Self

Retargets the track from its sampled value and velocity.

pub fn sample_at(&self, now: Duration) -> MotionScalarSample

Samples the track at the provided controller time.

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

Returns whether this track needs another adapter-owned frame.
