Enum FillRecipe 

pub enum FillRecipe {
    Solid(RecipeColor),
    StateLayer {
        base: RecipeColor,
        overlay: RecipeColor,
        alpha: f32,
    },
    LinearGradient {
        stops: Vec<GradientStop>,
        angle_deg: f32,
    },
    RadialGradient {
        stops: Vec<GradientStop>,
        center: (f32, f32),
        radius: f32,
    },
    None,
}

What the inside of the ShapeRecipe is filled with.

Solid and StateLayer both resolve to a flat Color (the latter by compositing an overlay over a base at a given alpha — the Material-3 / Fluent “state layer” model). LinearGradient / RadialGradient describe true gradients; the renderer paints them via the SDF gradient pipeline once a PaintProp carries them (see resolve_fill_to_paint).

Variants

Solid(RecipeColor)

Single flat color.

StateLayer

overlay composited over base at alpha — a translucent “state layer” (M3 hover = 8 %, pressed = 12 % on-color over the base fill). Resolves to a flat Color, so it flows through the solid paint path with no gradient support required.

Fields

base: RecipeColor

overlay: RecipeColor

alpha: f32

LinearGradient

Linear gradient at angle_deg (0° = top→bottom, 90° = leading→trailing).

Fields

stops: Vec<GradientStop>

angle_deg: f32

RadialGradient

Radial gradient with normalized center (0.0..=1.0) and radius in normalized units of the bounding rect’s longer side.

Fields

stops: Vec<GradientStop>

center: (f32, f32)

radius: f32

None

No fill (transparent).

Implementations

impl FillRecipe

pub fn solid(color: impl Into<RecipeColor>) -> Self

pub fn state_layer( base: impl Into<RecipeColor>, overlay: impl Into<RecipeColor>, alpha: f32, ) -> Self

A translucent state layer: overlay composited over base at alpha (clamped to 0.0..=1.0). Resolves to a flat Color.

pub fn resolve_flat(&self, colors: &ColorTokens) -> Option<Color>

Resolve the flat-color variants (Solid, StateLayer, None) against colors. Gradient variants return None here — they are resolved to a Paint by resolve_fill_to_paint, not to a flat color. FillRecipe::None maps to Some(Color::TRANSPARENT).
