Enum RenderNode 

pub enum RenderNode {
    Primitive(PrimitiveEntry),
    DrawRun(DrawRunNode),
    Layer(Box<LayerNode>),
}

A child of a layer in the render graph.

Variants

Primitive(PrimitiveEntry)

A single draw or text primitive.

DrawRun(DrawRunNode)

A whole draw command’s primitives as one node. A heavy canvas records thousands of primitives per frame; wrapping each in its own RenderNode made the graph rebuild move every one of them twice and free seventeen thousand nodes per frame on a stress scene. The run keeps the recorded vector intact — semantically it is exactly that many consecutive Primitive draw entries with no per-primitive clip.

Layer(Box<LayerNode>)

A nested layer.

Implementations

impl RenderNode

pub fn draw_phase(&self) -> Option<PrimitivePhase>

The phase the node paints in among its layer’s own draws: a primitive’s or run’s, or a draw group layer’s. None for the layer of a layout node, which is a child of the layer.

Trait Implementations

impl Clone for RenderNode

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
