Trait for handling different record format versions

Required Methods

fn record_header_size(&self, key_len: usize) -> usize

Calculate the size of a record on disk (excluding value)

fn total_size(&self, key_len: usize, value_len: usize) -> usize

Calculate total size including value

fn serialize_record(&self, record: &Record, include_value: bool) -> Vec<u8>

Serialize a record to bytes for disk storage

fn parse_record(&self, data: &[u8]) -> Option<(Vec<u8>, usize, u64, u64)>

Parse a record from disk bytes (returns key, value_len, timestamp, ttl_expiry)

fn value_offset(&self, key_len: usize) -> usize

Get the offset where value data starts in the serialized format

Provided Methods

fn serialize_record_into( &self, record: &Record, include_value: bool, data: &mut Vec<u8>, )

Append a serialized record without its sector header.
