Module vector 

Backend-agnostic SVG/vector asset IR.

usvg owns SVG normalization: XML, inherited style, transforms, arcs, relative commands, and basic shapes are resolved before Aetna stores anything. The renderer-facing IR below is deliberately small: paths plus fill/stroke style. Backends can tessellate it with lyon or feed it into more specialized vector shaders later.

Structs

PathBuilder

Imperative builder for a single VectorPath. Mirrors a subset of the SVG path command vocabulary (M, L, C, Q, Z) plus fill/stroke style. Returns a VectorPath; combine multiple via VectorAsset::from_paths.

VectorAsset

VectorFill

VectorGradientStop

A gradient stop. The colour is stored in linear premultiplied-friendly floats (sRGB → linear, with the per-stop opacity baked into the alpha) so vertex interpolation matches what the shader expects.

VectorParseError

VectorPath

VectorRadialGradient

Enums

IconMaterial

VectorColor

VectorFillRule

VectorGradient

A linear or radial gradient resolved to absolute SVG/viewBox space. The stored axis/centre coordinates live in the gradient’s own coordinate system; absolute_to_local maps a point in absolute SVG space back into that system so per-vertex evaluation is one matrix-multiply away.

VectorLineCap

VectorLineJoin

VectorRenderMode

Render policy for app-supplied VectorAssets.
