Module store 

Persistent session store — pluggable backend for session state.

Sessions are serialized to JSON and stored via a SessionStore backend. On coordinator restart, sessions are loaded from the store and restored to their last-persisted state.

OCP design

New backends (Redis, PostgreSQL, S3) are added by implementing the SessionStore trait.

Structs

FileSessionStore

File-based session store. Each session is a JSON file in a directory.

InMemorySessionStore

In-memory session store (default, no persistence).

SessionSnapshot

Serialized session snapshot — the unit of persistence.

Enums

StoreError

Errors during store operations.

Traits

Trait for session persistence backends.
