mnem-backend-redb

Production embedded-KV backend for mnem - redb-backed Blockstore and OpHeadsStore.

Implements the two storage traits from mnem-core against redb, a pure-Rust embedded ACID key-value store. A single .redb file holds objects (CID bytes to object bytes) and op_heads (CID bytes to unit, presence-as-truth). Writes are atomic per-call: each put / delete opens a write transaction and commits, which fsyncs. redb serialises writers inside a process and uses filesystem locking across processes. Picked as the sole v1 durable backend per for its pure-Rust dependency surface, mmap reads, and ACID semantics.

use mnem_backend_redb::open_or_init;
use mnem_core::repo::ReadonlyRepo;

let (bs, ohs, _path) = open_or_init("/tmp/agent.redb")?;
let repo = ReadonlyRepo::init(bs, ohs)?;
