Struct MotionSpring 

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

The design-token vocabulary: the Theme bundle plus its component token tables, flat-re-exported from frust-theme so app code never names that crate directly. A root component reads the active theme via use_context::<Theme>(); a widget reads it during paint/layout via PaintCtx::theme_as/LayoutCtx::theme_as (or Theme::from_paint_ctx).

Includes the glass material tokens — this crate ships the opaque recipe, and a design system authors its own translucent one over the same types:

use frust::GlassScale;

let glass = GlassScale::opaque_material();
assert_eq!(glass.chrome.blur_radius_intent, 0.0);
assert!(glass.control.is_opaque());

Also the composable-theming surface: ThemeBuilder (defineTheme/copyWith analog), the no-lock-in typed extension slot (ThemeExtensions) plus its first consumer StatusPalette/StatusColors (success/warning/info), and the motion vocabulary (MotionDurations/EasingSet) — all flat-re-exported so an app (or a design-system plugin) authors a theme against frust::* alone. A physics spring’s damping ratio and stiffness (mass is implicitly 1.0 for every preset; see module docs).

Fields

damping_ratio: f64

stiffness: f64

Trait Implementations

impl Clone for MotionSpring

fn clone(&self) -> MotionSpring

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MotionSpring

impl Debug for MotionSpring

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<MotionSpring> for SpringDesc

Converts a MotionSpring token into the generic physics type AnimationController::fling/ Spring::new consume.

Mass is always 1.0 — every preset (this crate’s and each design system’s own) is defined purely in terms of damping ratio + stiffness, so mass has no token-level source to convert from.

fn from(spring: MotionSpring) -> SpringDesc

Converts to this type from the input type.

impl PartialEq for MotionSpring

fn eq(&self, other: &MotionSpring) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
