Struct MotionSpring 

pub struct MotionSpring { /* private fields */ }

A deterministic scalar spring transition.

Implementations

impl MotionSpring

pub fn new( spec: MotionSpringSpec, from: f32, target: f32, initial_velocity: f32, started_at: Instant, ) -> Self

Creates a scalar spring transition.

pub fn retarget_from_sample( spec: MotionSpringSpec, sample: MotionScalarSample, target: f32, started_at: Instant, ) -> Self

Creates a new spring whose source and velocity come from an interrupted sample.

pub const fn spec(self) -> MotionSpringSpec

Returns the spring specification.

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) -> Instant

Returns the instant at which the spring started.

pub const fn cancelled_at(self) -> Option<Instant>

Returns the instant at which the spring was cancelled.

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

Marks the spring as cancelled at the provided instant.

pub fn sample(self, now: Instant) -> MotionScalarSample

Samples the spring at the provided instant.

pub fn sample_elapsed( spec: MotionSpringSpec, from: f32, target: f32, initial_velocity: f32, elapsed: Duration, ) -> MotionScalarSample

Samples a spring using an explicit elapsed duration.
