Crate crdt_store 

crdt-store

Persistence backends for crdt-kit.

Provides a unified storage abstraction for persisting CRDT state and operation event logs across different backends: SQLite, redb, in-memory, and raw flash (for no_std IoT).

Quick Start

use crdt_store::{MemoryStore, StateStore};

let mut store = MemoryStore::new();
store.put("sensors", "sensor-42", b"hello").unwrap();
let data = store.get("sensors", "sensor-42").unwrap();
assert_eq!(data.as_deref(), Some(b"hello".as_slice()));

Backends

Backend	Feature flag	Use case
MemoryStore	(always available)	Testing, prototyping
SqliteStore	sqlite	Edge Linux, mobile, desktop
RedbStore	redb	Pure-Rust edge without C deps
