Helix fails to correctly configure rust analyzer?

[tommasoclini]

Summary

This is a sample project: https://github.com/tommasoclini/esp_rust_ws
Helix fails to work completely correctly, for example, when editing from the upper workspace directory, warnings on unused imports do not get shown in the app.
vscode works completely fine instead.

Reproduction Steps

I tried this:

Project layout in rust like this

I expected this to happen:

Language features should work correctly in both platform-agnostic and platform specific code.

Instead, this happened:

Language features do not work well in the app(platform specific part), while vscode and neovim do(neovim uses rustaceanvim to pick up settings from .vscode/settings.json).

I had issues with esp-generate projects in NeoVim and resolved it by restructuring projects to more standard main.rs under src.

Looks like your project is also structured like that based on this in cargo.toml

[[bin]]
name = "my_app"
path = "./src/bin/async_main.rs"

The even weirder thing is that neovim works well with my current project structure, what plugins did you use for rust?

I'm using LazyVim, it comes with rustaceanvim.

Me too, even weirder!

Me too, even weirder!

All these configs are so complex and sensitive to exact versions of every tool that no two computers are alike.

I can say that in the last week or so I started having strange issues, like go-to-definition (gd) sometimes brings me to an empty file first time with error notifications (which I haven't read yet), second time it usually works, and other issues like that.
The only thing I changed recently was upgrade esp toolchain to the latest to work with the latest esp-hal. I don't see why it should affect this, but maybe it does.

Do you have the latest version of everything lazyvim related? Including neovim of course. Have you checked LazyHealth?
I manage my neovim installations with the bob crate: cargo install bob.

I updated yesterday LazyVim plugins, not sure if it updates everything (like Mason installations etc.)
Didn't yet have the energy to dive into these things.
LazyHealth looks fine.

I manage my neovim installations with the bob crate: cargo install bob.

Never heard of it, will check it out, thanks.

Is there something wrong with it?
I've noticed sometimes neovim fails too, this is the error message from rust analyzer:
