Rust is a programming language with a knack for ergonomics in a space where robustness, correctness, and speed often come at the cost of many papercuts. Nix is a project focused on building software in a robust, correct, and deterministic way. These two projects should be best friends, right? In this talk Zach Mitchell from flox and the Documentation Team will give an experience report writing Rust bindings for Nix. What makes bindings difficult? Which bindings can be autogenerated? Which can (or should) be written by hand? Tune in to find out what went well, what was painful, and what didn't work at all.
