Enum RenderNode 

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

Variants

Primitive(PrimitiveEntry)

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>)
