Rust project: file not included in module tree

[zjp-CN]

I'm reading cross-term's example interactive-demo. And I open the source file with helix (master version), and get a single error from rust-analyzer file not included in module tree on the first line.

git clone https://github.com/crossterm-rs/crossterm.git
cd examples/interactive-demo
hx src/main.rs

Hover doc, autocompletion and goto-definition are not working. But you can see they work in neovim (under examples/interactive-demo too):

helix-nvim.mp4

This is the expected behavior of the current workspace detection - the crossterm repo's root is the highest directory in the git repository that has a root marker (Cargo.toml). Rust-analyzer thinks that the module isn't included because it isn't included in crossterm (which is correct) rather than the interactive-demo project. Also see #3993, #2732, #2970

@pascalkuthe do you think this and related issues are reasonably solved #5748

[pascalkuthe]

yeah that's fixed by that PR specifying editor.workspace-lsp-roots = ["examples/interactive-demo"] in a .helix/config.toml file inside the crossterm repo works. There is no situation to autodetect stuff like this and exactly why we ended up with the implementation in #5748

I forgot to link this issue in that PR, thanks 👍
