enum SessionWrite {
Overwrite,
KeepExisting,
}Expand description
Merge an in-memory record into an on-disk file’s raw JSON, preserving fields beyond this binary’s struct shape.
Returns Ok(None) when the writer must refuse the merge (corrupt
JSON, missing schema_version, or schema_version above
MAX_SUPPORTED_SCHEMA). The caller treats None as a skip and
leaves the on-disk file intact.
Whether an upsert may replace the record’s session_id.
