Struct AnimationSpec 

pub struct AnimationSpec {
    pub duration_ms: f32,
    pub delay_ms: f32,
    pub timing: Timing,
}

How long a change takes and along which curve.

A role is the default way to say this (MotionRole), and the design system answers it; this is the escape hatch for a screen whose author has already decided, as CSS does. Without one, AnimationSpec::STANDARD is used: the standard motion of Material 3, the length and curve the design systems’ own standard role is built on.

Fields

duration_ms: f32

delay_ms: f32

timing: Timing

Implementations

impl AnimationSpec

pub const STANDARD: Self

300 ms along cubic-bezier(0.2, 0, 0, 1).

pub const fn tween(duration_ms: f32, timing: Timing) -> Self

A change of duration_ms along timing, starting at once.
