 Ralith | how do those compare to the mozilla overlay? | 06:05:19 |
 dpc | Does jumping to definition of a private method supposed to work in rust-analyzer? | 06:11:27 |
| dpc | It doesn't here, and I wonder if this is kak-lsp or rust-analyzer's doing. | 06:11:45 |
| dpc | It's a pita, when a symbol is accidentally private and I can't jump to it to add pub | 06:12:05 |
| dpc | BTW. I also use fenix exclusively. I had some problems with nix flakes and mozilla overlay and tried fenix, worked like a charm and never felt a need to go back. | 06:15:22 |

Depending on your use case, you might need to set the --impure flag when invoking the nix command. This is because this repository fetches resources from non-pinned URLs non-reproducibly.

| schuelermine | Hi, I just installed Rust via Nix, and I’m getting an error when using the rust-analyzer extension for VSCode.
“Failed to find sysroot for Cargo.toml file”. It asks if rust-src is installed. How can I install the Rust sources via Nix? | 09:14:04 |
 a-kenji | Oh, I haven't used vscode in a while, but that error does ring a bell. Do you have rust analyzer itself installed in nix?
| 09:15:29 |
| a-kenji | And is the extension installed through the marketplace, or nix? | 09:15:47 |
| schuelermine | Yes, I have rust-analyzer installed via Nix. But it might still be using a downloaded version, there was a downloading message. | 09:16:27 |
| schuelermine | The extension is from the marketplace | 09:16:35 |
| a-kenji | Ah, maybe it makes sense to try it out with one of the mentioned overlays and to install rust analysis itself.
| 09:17:24 |
| a-kenji | I use a form of the following rust-toolchain.toml usually: ```
[toolchain]
channel = "1.62.0"
components = ["rustfmt", "clippy", "rust-analysis"]
targets = []
| 09:17:47 |

| 09:18:01 |
| schuelermine | I have downloaded oxalica’s rust overlay and it includes rust-src. I will try using it! | 09:26:42 |
| schuelermine | Is there a difference between rust-analysis and rust-analyzer? | 09:29:56 |
| schuelermine | Hmm, it doesn’t seem to discover it | 09:59:38 |
| schuelermine | It expects it to be installed where rustc is installed, but the command it uses to find that backtracks through the nix profile symlinks back into the store, where they’re separate of course. | 10:00:26 |
| schuelermine | Does anybody know if this can be fixed? Or should I just use rustup? | 10:00:49 |
| a-kenji | https://nixos.wiki/wiki/Rust | 11:24:11 |
| a-kenji | Under shell.nix example is something I have used in the past: ```
Certain Rust tools won't work without this
This can also be fixed by using oxalica/rust-overlay and specifying the rust-src extension
See https://discourse.nixos.org/t/rust-src-not-found-and-other-misadventures-of-developing-rust-on-nixos/11570/3?u=samuela. for more details.

| a-kenji | I am not 100% sure if the path is actually correct anymore I remember having to do something like "${pkgs.rust.packages.stable.rustPlatform.rustLibSrc}"/lib/src, or something like that. | 11:25:37 |
 kayla.fire | In reply to@schuelermine:matrix.org
Does anybody know if this can be fixed? Or should I just use rustup? I've had vscode+nix+rust working before, but I've forgotten the exact steps I've used at this point because I use crane now.
But when using rust though a nix devshell, I always add nativeBuildInputs = [ cargo rustc ]; to a mkShell invocation and then launch vscode from that devshell, to make rust-analyzer work.
I've basically found that to get rust-analyzer to work I've gotta launch vscode from the devshell for the project
But I also use declarative vscode so I'm not sure if that's a big enough difference here | 13:20:46 |
