Struct GlassScale 

pub struct GlassScale {
    pub chrome: GlassMaterial,
    pub bar: GlassMaterial,
    pub control: GlassMaterial,
}

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. The three glass tiers a Theme carries: chrome (popovers/sheets/menus), bar (tab/nav/toolbars), and control (buttons/toggles). See the module docs for each tier’s source recipe.

Fields

chrome: GlassMaterial

Popovers, sheets, menus — the most opaque, highest-blur tier.

bar: GlassMaterial

Tab bars, nav bars, toolbars — a subtle mid-blur tier.

control: GlassMaterial

Buttons, toggles — a pure low-blur lens, no fill.

Implementations

impl GlassScale

pub fn opaque_material() -> GlassScale

The opaque scale: every tier is opaque — blur_radius_intent == 0.0 and empty fill stacks — so a widget reading GlassMaterial::is_opaque paints its surface-container role instead of a translucent lens. This is the “one API on either design language” seam: the same widget code reads theme.glass.<tier> and branches on is_opaque().

Shadows reuse the Elevation::neutral table so the opaque path lines up with that elevation ladder: chrome = level 3 (menus/dialogs), bar = level 2 (nav bar), control = level 1.
