Module sync15::migrate_state

Functions

extract_v1_state

Given a string persisted as our old GlobalState V1 struct, extract out the sync IDs for the collection, plus a string which should be used as the new "global persisted state" (which holds the declined engines). Returns (None, None) in early error cases (eg, invalid JSON, wrong schema version etc). Otherwise, you can expect the returned global state to be Some, even if the CollSyncIds is None (which can happen if the engine is missing, or flagged for reset)
