}Expand description
Versioned slice for zero-copy access
Holds a reference to data along with visibility metadata, avoiding copies during scan iteration.
Fields§
§key: &'a [u8]Key bytes (zero-copy reference)
value: Option<&'a [u8]>Value bytes (zero-copy reference, None = tombstone)
commit_ts: u64Commit timestamp (0 = uncommitted)
txn_id: u64Transaction ID that wrote this version
