Struct MaterialSpring 

pub struct MaterialSpring {
    pub stiffness: f64,
    pub damping_ratio: f64,
}

A Material 3 Expressive spring preset: stiffness plus damping_ratio (mass implicitly 1.0 — see the module docs). 1.0 is critically damped (no overshoot); values below 1.0 overshoot before settling.

Fields

stiffness: f64

damping_ratio: f64

Implementations

impl MaterialSpring

pub const SPATIAL_FAST: Self

Fast spatial spring for size/position/shape morphs — feeds motion_scheme’s fast_spatial.

pub const SPATIAL_DEFAULT: Self

Default spatial spring for size/position/shape morphs — feeds motion_scheme’s default_spatial.

pub const SPATIAL_SLOW: Self

Slow spatial spring for size/position/shape morphs — feeds motion_scheme’s slow_spatial.

pub const AOSP_SPATIAL: Self

AOSP spatial spring (matches AOSP notification-list expansion — no overshoot). No MotionScheme slot; a crate-reachable constant only.

pub const EXPRESSIVE_SPATIAL_FAST: Self

Fast expressive spatial spring with slight overshoot. No MotionScheme slot; a crate-reachable constant only.

pub const EXPRESSIVE_SPATIAL_DEFAULT: Self

Default expressive spatial spring with slight overshoot. No MotionScheme slot; a crate-reachable constant only.

pub const EXPRESSIVE_SPATIAL_PRESS: Self

Interactive press-scale spring (floating toolbar / button morph recipe). No MotionScheme slot; a crate-reachable constant only.

pub const EXPRESSIVE_SPATIAL_SLOW: Self

Slow expressive spatial spring with slight overshoot. No MotionScheme slot; a crate-reachable constant only.

pub const EFFECTS_FAST: Self

Fast effects spring for color/opacity (no overshoot) — feeds motion_scheme’s fast_effects.

pub const EFFECTS_DEFAULT: Self

Default effects spring for color/opacity (no overshoot) — feeds motion_scheme’s default_effects.

pub const EFFECTS_SLOW: Self

Slow effects spring for color/opacity (no overshoot) — feeds motion_scheme’s slow_effects.
