Struct GlassMaterial 

pub struct GlassMaterial {
    pub blur_radius_intent: f64,
    pub fills_light: Vec<GlassFill>,
    pub fills_dark: Vec<GlassFill>,
    pub hairline_alpha: f32,
    pub shadow: ShadowSpec,
}

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. One glass tier’s recipe: how much background blur it intends, the translucent washes to composite over light and over dark content, its specular hairline alpha, and its drop shadow.

blur_radius_intent is an intent in the kit’s blur units, not a rendered pixel radius — a later painting task maps it to the platform’s blur primitive. 0.0 means “no lens”: the opaque-material path (see GlassMaterial::is_opaque).

Fields

blur_radius_intent: f64

Background-blur intent in a design system’s own blur units; 0.0 is “no lens”, the opaque path GlassScale::opaque_material takes.

fills_light: Vec<GlassFill>

Washes composited over light content, bottom-to-top.

fills_dark: Vec<GlassFill>

Washes composited over dark content, bottom-to-top.

hairline_alpha: f32

Alpha of the specular hairline edge (white over light, drawn by the consuming widget). 0.0 on the opaque path.

shadow: ShadowSpec

The tier’s drop shadow.

Implementations

impl GlassMaterial

pub fn is_opaque(&self) -> bool

true when this material carries no background-blur intent — the opaque-material path a widget takes on the Material design language, where it paints its surface-container role instead of a lens. The single-API branch that lets one widget read either design language.
