Module serialized_key 

This module implements a zero-copy/optimized byte representation for keys in Fxfs.

Its goal is to facilitate lexicographically comparable key serialization, permitting optimal byte representations when performing operations across persistent layer structures in LSM trees.

Structs

KeyDeserializer

Handles decoding of sequential serialized key payloads.

KeySerializer

Serializes keys sequentially into binary format suitable for lexicographical comparisons.

KeySerializerFinalized

Proof token returned when key serialization has finalized its length headers.

Constants

MAX_CHUNK_LEN

Maximum length of a single key serialization chunk payload.

Traits

MergeSerializerOutput

Combines two SerializeKey::Output types across enum variants: produces KeySerializer<'a, B> if both variants are non-terminal, or KeySerializerFinalized if either variant is terminal.

SerializeKey

Trait defining the translation logic from Fxfs types into order-consistent binaries.

Functions

compare_keys

Evaluates comparison ordering between two serialized keys located at the beginning of a and b.
