Anyone have issues with VSCode's rust-analyzer on Nix in VSCode? I have a direnv set to use the flake, with the Rust I want to use installed, and vscode runs the extensions with it too. But yet, it seems to be a version mismatch, even with all my testing telling me they're both 1.95
Silly question, but what does your path / (dev)shell.nix look like? | 18:06:04 |

LogN | https://github.com/zirco-lang/zrc/blob/main/flake.nix | 18:13:32 |
LogN | The metadata agreed the rustc version I thought was what seemed to be building but idk how that affects cargo check or the RA server | 18:13:58 |
LogN | I previously didn't add the rust-analyzer feature because it worked until recently with no change afaik | 18:14:30 |
Ben Sparks | echo $PATH in vscode, check that your settings.json isn't doing odd thing etc. | 18:14:53 |
Ben Sparks | Use direnv and point it at your flake.{nix,lock} | 18:15:32 |
LogN | Nothing special about it in my settings afaik, I'll check the PATH when I get home. I use direnv, both the VSCode extension and for my shells | 18:16:16 |
Ben Sparks | You can also try to provide cargo and rust from the overlay, by pointing them at variables given by rust-overlay :) there's a lot to try here, so I think you'll find something | 18:18:05 |
LogN | hopefully yea, i'll give it a try | 18:26:59 |
LogN | Using rustup rust-analyzer in contrast to rust-bin appears to work | 18:58:10 |
