Module protocol 

Sync protocol abstraction — SyncHandle, SyncUpdate, SyncError. Sync protocol trait — abstraction over SVS, PSync, etc.

Consumers don’t choose a sync protocol directly; they subscribe to a group prefix and the runtime picks the appropriate protocol.

Structs

SyncHandle

Handle to a running sync group.

SyncUpdate

A notification that new data is available from a peer.

Enums

SyncError

Error type for sync protocol operations.
