-//! This module contains the encoding and decoding of the local manifest file.
-//!
-//! MANIFEST is a write-ahead log which is stored locally to each timeline. It
-//! records the state of the storage engine. It contains a snapshot of the
-//! state and all operations proceeding that snapshot. The file begins with a
-//! header recording MANIFEST version number. After that, it contains a snapshot.
-//! The snapshot is followed by a list of operations. Each operation is a list
-//! of records. Each record is either an addition or a removal of a layer.
-//!
-//! With MANIFEST, we can:
-//!
-//! 1. recover state quickly by reading the file, potentially boosting the
-//!    startup speed.
-//! 2. ensure all operations are atomic and avoid corruption, solving issues
-//!    like redundant image layer and preparing us for future compaction
-//!    strategies.
-//!
-//! There is also a format for storing all layer files on S3, called
-//! `index_part.json`. Compared with index_part, MANIFEST is an WAL which
-//! records all operations as logs, and therefore we can easily replay the
-//! operations when recovering from crash, while ensuring those operations
-//! are atomic upon restart.
-//!
-//! Currently, this is not used in the system. Future refactors will ensure
-//! the storage state will be recorded in this file, and the system can be
-//! recovered from this file. This is tracked in
-//! https://github.com/neondatabase/neon/issues/4418
