16:15 <evanjs> evils: yeah you really don't need much for a rust shell (example here -- https://github.com/evanjs/rbooru/blob/master/shell.nix -- but note that I can do `pkgs.latest.rustChannels` bc https://github.com/evanjs/nixos_cfg/blob/99876f003ee63c0c9f7beba5114ccc9c94b67ca0/config/new-modules/dev/rust.nix#L92)

16:16 <evanjs> It's basically the same as using this https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/rust.section.md#controlling-rust-version-inside-nix-shell

16:16 <evanjs> And replacing "nightly" with "stable", "beta", etc

16:17 <evanjs> Stable is good if you don't want to deal with bugs. Nightly is good if you want to make sure your code is compatible with upcoming Rust releases, and catch changes before you have to make big changes down the line

16:17 <evanjs> Beta is a good balance between the two

16:20 <evanjs> I just run a lorri daemon in the background and always have an up to date rust (± 6 hours for nightly) as the nixpkgs mozilla overlay sources the same stuff rustup does, and lorri just watches in the background to make sure everything is always up to date

23:38 <evils> evanjs: thanks, i again managed to forget nix has documentation...

23:39 <evils> the rust overlay is just for more up-to-date rust? do i understand you right that lorri overwrites the rev you specified?

23:45 <evils> the issue i was having was due to putting an `exec zsh` `shellHook` in my shell.nix, which i've currently got down to just adding `rustup`, at least until i get a bit familiar with the tooling, and `RUST_BACKTRACE = 1`, cause everyone seems to do that :P, and am using `lorri shell` without the daemon and setup
