Struct SpringSpec 

pub struct SpringSpec {
    pub damping_ratio: f32,
    pub stiffness: f32,
    pub velocity_threshold: f32,
    pub position_threshold: f32,
    pub delay_millis: u64,
}

Spring animation configuration.

Fields

damping_ratio: f32

Damping ratio. 1.0 = critically damped, < 1.0 = under-damped (bouncy), > 1.0 = over-damped.

stiffness: f32

Stiffness constant. Higher values = faster animation.

velocity_threshold: f32

Velocity threshold to stop animation.

position_threshold: f32

Position threshold to stop animation.

delay_millis: u64

Delay before the spring begins advancing.

Implementations

impl SpringSpec

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

Create a spring with explicit Compose-style physics constants.

pub fn with_delay(self, delay_millis: u64) -> Self

Add a delay before the spring starts integrating.

pub fn default_spring() -> Self

Create a spring with default material design values.

pub fn bouncy() -> Self

Create a bouncy spring.

pub fn stiff() -> Self

Create a stiff spring (fast, no bounce).
