Rust Inside™
A Python binding to rust-postgres, a native PostgreSQL driver for Rust.
IRC channel: #slonik on freenode.
Note: Slonik started as an experiment, and will probably never go past that. We've learned tons of things during its creation, two of them being that programs using CFFI are bound to be slower (with CPython) than implementations using the Python C API, and that interfacing the Python Event Loop with the async support of Rust is… challenging at best.
