Struct MaterialSpringEasing 

pub struct MaterialSpringEasing { /* private fields */ }

Bridges a physical spring to FerroUI’s normalized-progress IEasing interface.

Use the matching duration; the same spring with an unrelated duration changes its physical speed. This adapter starts with zero velocity because IEasing has no velocity channel. Controls needing interruption continuity use MaterialSpringState instead.

Implementations

impl MaterialSpringEasing

pub fn new( spec: MaterialSpringSpec, duration: TimeSpan, reduced_motion: bool, ) -> Self

pub fn spring_spec(&self) -> MaterialSpringSpec

Parameters consumed by the velocity-preserving Material property transitions.

Trait Implementations

impl Clone for MaterialSpringEasing

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaterialSpringEasing

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

Formats the value using the given formatter.

impl IEasing for MaterialSpringEasing

fn ease(&self, progress: f64) -> f64

Returns the transformed value for a linear progress.

fn to_shared(&self) -> Arc<SharedEasing>

The easing as the render thread evaluates it: a key frame animation of the compositor runs there. An easing without parameters returns itself; one with parameters returns a copy with the parameters it has now.

fn derives_from_easing(&self) -> bool

Whether the object is an easing class: upstream, a class deriving from the Easing base class, which code tests for with a cast. True for every easing of this module and by default, because implementing this trait is how an easing class is written here; an object that stands for a bare implementation of the contract (not an easing class) answers false.
