Struct DrawRunNode 

pub struct DrawRunNode {
    pub phase: PrimitivePhase,
    pub command: Option<DrawCommandId>,
    pub recording: Rc<CommandRecording>,
    pub segments: Range<u32>,
    pub summary: DrawRunSummary,
}

Fields

phase: PrimitivePhase

command: Option<DrawCommandId>

Which draw command recorded these primitives. None only for runs with no per-command provenance (hand-built tests).

recording: Rc<CommandRecording>

Shared, not owned: the recording registry keyed by DrawCommandId keeps a handle to the same recording, so its buffers survive this node being dropped on the next rebuild and the command re-records into them. Nothing mutates a recording after construction, which is what makes sharing sound.

segments: Range<u32>

The segments of the recording this run draws: one placement’s part of a with-content command, or the whole recording.

summary: DrawRunSummary

Content facts consumers keep asking per frame, answered while recording and never by rescanning.
