RecordRef
What MemoryProvider.remember returns: the stored record's id and version.
Fields
idstringrequiredThe provider's id for the record, non-empty. The model passes it to forget_memory; local_memory derives it from the write's key, so a retried save returns the same id.
versionstringrequiredThe provider's version of the record, non-empty. local_memory always returns "1" (records never change).
