Struct CoverageReadbackState

Source

pub struct CoverageReadbackState {
    pub inflight: bool,
    pub pending_snapshot: Option<Vec<(MeshKey, u32)>>,
}

Expand description

Per-frame state for the GPU coverage readback loop.

The renderer dispatches coverage after geometry, copies the counts into a CPU-mappable buffer, and kicks a mapAsync that resolves on a future frame. To keep the path single-buffered, inflight short-circuits the next kick while a prior mapAsync hasn’t yet resolved; pending_snapshot carries the resolved (MeshKey, count) pairs back to the next render frame which calls MeshCoverage::ingest.
