A frame is a non-empty array of ops (order is significant). Op frame processing is transactional: A frame is either processed in its entirety or not processed at all. While ops are immutable, frames of ops get routinely created and rehashed.
Swarm RON frames provide:
- lightweight transactional semantics,
- frame-level op compression that fully exploits the fact that close UIDs tend to be close numerically,
- a great unifying abstraction:
- an object's state is a frame;
- reducers consume frames and produce frames,
- a patch is a frame carrying a difference between two states,
- an object graph snapshot is a frame too,
- a single op travels around as a frame of one op.
Apart from immutable payload ops, a frame may have its own header op. A header op consists of:
- reducer id (the one that produced the frame),
- object id (or 0 for omnivorous reducers),
- end version (most often, the last reduced op id),
- start version (actual for patches).
- void value (
