Struct ShapingRouteCapabilities 

pub struct ShapingRouteCapabilities {
    pub route_kind: ShapingRouteKind,
    pub is_pixel_deterministic: bool,
    pub supports_fallback_fonts: bool,
    pub supports_color_emoji: bool,
    pub supports_bidi: bool,
    pub max_paragraph_bytes: usize,
}

Declared capabilities and operating boundaries of a shaping route.

Plan §10.9 & §13.2: Honest capability reporting and context bounds.

Fields

route_kind: ShapingRouteKind

Route classification.

is_pixel_deterministic: bool

Whether runs from this route are bit-identical across machines/OS versions.

supports_fallback_fonts: bool

Whether this route can resolve and substitute platform fallback fonts.

supports_color_emoji: bool

Whether this route supports color emoji or bitmap glyphs.

supports_bidi: bool

Whether this route handles bidirectional text (LTR and RTL).

max_paragraph_bytes: usize

Maximum byte length allowed for a single shaping invocation (Plan §10.9).

Exceeding this budget yields NativeShapingError::ContextBudgetExceeded.
