rust-analyzer won't work on this rustlings repo

[7--]

I'm doing Rustlings excersises. If I clone this Rustlings repo rust-analyzer works fine. https://github.com/rust-lang/rustlings

I created my own repo for Rustlings so I can save my work. This repo won't work with rust-analyzer reguarless of commit number. I tried cloning a new copy then checking out a bunch of old commits in the repo (before any of my changes) and oddly no version works at all. https://github.com/7--/rustlings

See if you can get rust-analyzer to work on this repo even using an old version. This repo was working fine at one point. rust-analyzer is the only extension I have installed in VS code.

You need to set "rust-analyzer.cargo.features": ["exercises"] in your editor configuration for the rustling workspace. Rustlings has an unusual project structure. This config causes rustlings to generate extra files necessary for rust-analyzer to understand the project structure if I understand rust-lang/rustlings#917 correctly.

[7--]

"rust-analyzer.cargo.features": ["exercises"]

I get this error when I put that line in my settings.json

What does git status show in your clone of the rustlings repo?

Never mind. You've started from an older version of rustlings, which doesn't contain the exercises feature/fix. You can probably copy over your source code changes.

I pulled from the Rustlings repo and fixed the conflicts and errors, but still rust-analyzer doesnt work. Not seeing any rust-analyszer errors. I'm already like 80% done with Rustlings so if it's just this repo I'll live without it.

@7-- Hi, maybe it's too late for it, but I had the same problem, rustlings lsp worked for me, I am using LunarVim though.

[JeppeKlitgaard]

I ran into this as well.

I can confirm that running rustlings lsp once solves the problem in VSCode as well.

[gachikuku]

I got neovim and running rustlings lsp solves the problem as well.

[cossieB]

For me rustlings lsp didn't quite work. It generated the rust-project.json file but autocomplete and type hints weren't working. Upon investigating I noticed that the 'sysroot_src' value in the json truncated my Windows user name - presumably because of the space in it. So I changed it to C:\Users\$MY_USER_NAME\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\src\rust\library. Now it works, although it's not showing some errors in the editor like a normal cargo project. I'm not sure if that's by design

[Veykril]

You mean the truncation happened on the r-a side or the path in the json file was truncated? If the latter it would be nice to report that to the rustlings repo.

Regarding the errors I am unsure, it might not work that well given the structure (I'm hoping to make rustlings work better with some design changes)

Basically this is what rustlings lsp generates

And this is what I changed it to

I just noticed that a bit more than my user name were truncated. Thanks I'll report this bug to the Rustlings team

Thanks for all the work you've been putting Rust Analyzer. The errors still show in the terminal so I'll manage.

I can confirm that the command still works if you have any problems regarding intellisense.

[bbkr]

Running rustlings lsp and restarting LSP server fixed the issue in Kate editor. Now I have code analysis and completion.
