Module storage 

On-disk snapshot storage.

The storage file is a small page container. A snapshot is encoded into a sequence of fixed-size pages, each page carrying its own length and CRC. This keeps the file format inspectable and lets recovery distinguish a complete snapshot from a torn write without relying on external crates.

Constants

MAX_SNAPSHOT_BYTES

Maximum encoded snapshot size accepted by the file and byte APIs.

MAX_SNAPSHOT_PAYLOAD_BYTES

Maximum state payload that can fit in a valid snapshot of the configured maximum size.

PAGE_SIZE

Functions

read_snapshot
