rkv

rkv is a usable Rust wrapper around LMDB.

It aims to achieve the following:

• Avoid LMDB's sharp edges (e.g., obscure error codes for common situations).
• Report errors via failure.
• Correctly restrict to one handle per process via a 'manager'.
• Use Rust's type system to make single-typed key stores (including LMDB's own integer-keyed stores) safe and ergonomic.
• Encode and decode values via bincode/serde and type tags, achieving platform-independent storage and input/output flexibility.
