Struct MotionScheme 

pub struct MotionScheme {
    pub shape: AnimationSpec,
    pub color: AnimationSpec,
    pub color_fast: AnimationSpec,
    pub overlay: AnimationSpec,
    pub spring: AnimationSpec,

}

Centralized animation specs for M3 motion design.

Fields

shape: AnimationSpec

Shape / size / bounds transitions (e.g., indicator position, elevation). M3 standard: 200 ms FastOutSlowIn.

color: AnimationSpec

Color state transitions (e.g., label, tab text, selection). M3 standard: 150 ms FastOutSlowIn.

color_fast: AnimationSpec

Quick color changes (e.g., checkbox fill, switch track, radio ring). M3 standard: 100 ms FastOutSlowIn.

overlay: AnimationSpec

Overlay / popup enter‑exit (menus, dialogs, tooltips). M3 standard: 120 ms FastOutSlowIn.

spring: AnimationSpec

Spring‑based positional animation (sheets, drawers, swipe‑to‑dismiss). M3 standard: gentle spring (ζ = 0.5, k = 200).

expand: AnimationSpec

Expanding containers (search bar, docked search suggestions). M3 standard: 250 ms FastOutSlowIn.

layout: AnimationSpec

Large layout transitions (bottom sheet height, scaffold reflow). M3 standard: 300 ms EaseOut.
