build(nix): move to unstable channel

[RaitoBezarius]

As NixOS 23.11 will be out soon and the shell.nix is broken due to MSRV requirements (23.05 has 1.69.0, not 1.70.0), we can already move to unstable which is "beta 23.11" at this point.

Checklist

• Sensible git history (for example, squash "typo" or "fix" commits). See the Rewriting History guide for help.
• Update the changelog (if necessary)

Hm, our nix shell comes with rustup. We don't use rustc from nixpkgs. What do you mean by it's not working then? rustup installs the proper toolchain.

NIX_PATH was rewired to the nixpkgs you provide inside that shell, therefore anyone who is not using rustup like me but rustc or cargo will only have errors on even basic checking. Le mar. 7 nov. 2023, 08:12, Philipp Schuster ***@***.***> a écrit :

I see. Personally, even on Nix, I'm a big rustup fan and don't like the "pure Nix"-way when it comes to Rust in a shell. But I see that some folks don't want to use rustup.

Instead of switching to nixpkgs-unstable, I think, a better solution would be to either
a) use rust-overlay and add the latest stable rust toolchain into the PATH
b) switch to a flake-based shell and provide one rustup shell and one with a pinned rustc.

What do you say?

I think a) or c) is fine where c) could be just the same setup with 2 shells attribute sets instead of a Flake as I don't think it's necessary at all.
