engine::piet_render_context

Structs

PietLayerRenderer

Retained metadata for one piet-backed browser canvas surface.

PietLayerTarget

Current piet surface set for one logical layer.

PietRenderer

RenderContext implementation backed by piet.

Implementations

new

pub fn new(layer_factory: impl Fn(usize) -> (PietLayerTarget<S>, Box<dyn Fn() -> LayerSurfaceLayout>) + 'static) -> Self

Create a piet renderer with a chassis-provided logical layer factory.

Traits

PietSurface

Chassis operations missing from Piet's portable API: reusable transparent surfaces and source-over composition with one opacity for the complete image.

Functions

fill_to_piet_brush

pub fn fill_to_piet_brush(fill: &Paint, rect: Rect) -> Option<PaintBrush>

Resolves a single paint to a Piet brush. Mixtures require the chassis paint accumulator, since generic Piet has no additive compositing operation.
