Struct Spring 

pub struct Spring {
    pub stiffness: f32,
    pub damping: f32,
}

A mass-1 spring. Stiffness sets speed, damping sets wobble: damping < 2·√stiffness is underdamped (overshoots and rings), anything above settles without crossing 1.

Fields

stiffness: f32

damping: f32

Implementations

impl Spring

pub fn new(stiffness: f32, damping: f32) -> Self

pub fn wobbly() -> Self

A bouncier preset (visible ring before settling).

pub fn stiff() -> Self

No overshoot at all (critically damped).

pub fn position(self, seconds: f32) -> f32

Spring position at time seconds, from 0 toward 1.

pub fn settle_seconds(self) -> f32

Seconds until the spring stays within 1% of the target — pass this as the Animation duration so the curve completes on screen.

pub fn easing(self) -> impl Fn(f32) -> f32 + 'static

The spring as a normalized easing over its settle duration.

Trait Implementations
