NixCon 2022

Write the Nix package of a Rust project in 2022: an opinionated comparison
10-21, 13:45–13:55 (Europe/Paris), Main track (Gym)

In this talk, we will address the different existing strategies to package an arbitrary Rust crate. Our goals are to try to minimize the amount of Nix code required to quick start, discussing how to deal with overlays, and finally demonstrating why Nix offers a greater cross-compilation developer experience than Cargo.

Existing solutions that will be compared are nixpkgs, naersk, crate2nix, cargo2nix and crane (used by dream2nix).

We will analyze what are the derivations produced for each of those and inspect how IFDs are used.

Do you allow your talk to be recorded? – yes What level of experience in Nix is the talk addressed to?
