Struct SpringSimulation 

pub struct SpringSimulation { /* private fields */ }

The shared animation layer — physics, curves, driver — see frus_core::animation. Re-exported here so applications can reach it through frus_widgets without depending on frus-core directly. A spring pulling a value from start towards end, started with an initial velocity. The reported position is end + solution(t).

Implementations

impl SpringSimulation

pub fn new( spring: SpringDescription, start: f32, end: f32, velocity: f32, tolerance: Tolerance, ) -> SpringSimulation

Builds a spring reaching from start to end, at initial velocity (px/s), with the given tolerance.

Trait Implementations

impl Clone for SpringSimulation

fn clone(&self) -> SpringSimulation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SpringSimulation

impl Debug for SpringSimulation

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

Formats the value using the given formatter.

impl Simulation for SpringSimulation

fn x(&self, time: f32) -> f32

The position at instant time.

fn dx(&self, time: f32) -> f32

The velocity — the derivative of position — at instant time.

fn is_done(&self, time: f32) -> bool

true once the motion has finished, within the tolerances.

fn tolerance(&self) -> Tolerance

The stopping thresholds.
