# lmdb-rs

Idiomatic and safe APIs for interacting with the
[Symas Lightning Memory-Mapped Database (LMDB)](http://symas.com/mdb/).

This repo is a fork of [mozilla/lmdb-rs](https://github.com/mozilla/lmdb-rs) that enables encryption of data at rest in LMDB.
lmdb-rs is itself a fork of [danburkert/lmdb-rs](https://github.com/danburkert/lmdb-rs)
with fixes for issues encountered by [mozilla/rkv](https://github.com/mozilla/rkv).
