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.

Feature choices

If you specify the backtrace feature, backtraces will be enabled in failure errors. This feature is disabled by default.

Contributing

rkv relies on the latest rustfmt for code formatting, please make sure your pull request passes the rustfmt before submitting it for review. See rustfmt's quick start for installation details.
