anyone's using vscode and rust-analyzer? I've tried about a dozen configurations now and each one breaks in a new and exciting way :) what I want to have is nix shell that's capable of building a rust project and packaging it into docker with the openssl (rustls is known broken for my use case) and a working rust-analyzer so I could write the code with some LSP support. My very latest iteration was trying to use ipetkov/crane but rust-analyzer fails on that with

[ERROR rust_analyzer::lsp_utils] rust-analyzer failed to load workspace: Failed to find sysroot for Cargo.toml file /home/nixos/src/kube-cidr-manager/Cargo.toml. Is rust-src installed?: can't load standard library from sysroot
/nix/store/n7m9l6djxf3xcdc2dk9scc6rbpw825p9-rustc-1.63.0

try installing the Rust source the same way you installed rustc

If I add RUST_SRC_PATH = "${pkgs.rust.packages.stable.rustPlatform.rustLibSrc}" to my mkShell attrs then rust-analyzer seems to work too. To some extent:

I've tried the rust-analyzer and vscode (read: codium) combo too, but can't get it to work... Would some kind soul here be willing to take a look at my below paste and tell me what I'm doing wrong?
The rust-analyzer extension keeps complaning when I start up vscode - other than that I have no error messages (it complains about missing binaries for my OS - NixOS).

This is my first time ever using VS Code for rust, and first time ever touching rust-analyzer. Reading the Rust wiki and the plugins' issues didn't help me understand where to go from here. Any pointers anyone?

I don't know how, but have you considered testing the fhs version in nixpkgs? I think it was referenced in the wiki page I linked in my above message.

In reply to @farcaller:matrix.org
nothing in the toolchain should require fhs per se, though, no?

I dunno, I only came across this in the wiki like I said. I'm really at a loss here myself on my own issues with rust-analyzer

I found a solution to my issue (I think - still veryfing/testing).

The rust-lang.rust-analyzer extension supports a "rust-analyzer.server.path": "rust-analyzer" setting, which can be put in <project/git repo root>/.vscode/settings.json. That along with the arrterian.nix-env-selector extension (and required shell.nix since I use flakes) seem to have done the trick for me.

Many thanks to @NobbZ on the Unofficial Nix/NixOS Discord Server for sharing the solution.
