Variants

NeedMemory

Answer with RevealSession::memory: can bytes more be allocated?

Fields

bytes: f64

stage: MemoryStage

NeedObservations

Pass every stored observation/ row to RevealSession::observation, then step again.

NeedTile(TileKey)

The tile is not resident: make room, insert it, step again.

Checkpoint

A compositor tile went into the reference; check for pause and stop, then step again.

Decode

Decode the recording for pass; wanted[i] marks the frames whose pixels it reads.

Fields

pass: Pass

wanted: Vec<bool>

NextFrame

The pushed frame is done: push the next one, or end the pass after the last.

PassDone(Pass)

The pass is over (its timings end here); step again for the next one.

Provenance(Provenance)

Store this canvas’s provenance row, then step again.

Done(Outcome)
