Hi @calidion, do you mind posting some context to the error message?

Quick question: jave you installed rls and and rust with the required components via rustup?

rustup update
rustup component add rls-preview rust-analysis rust-src

from https://github.com/eclipse/corrosion/blob/master/documentation/Troubleshooting.md

It is very obvious on vscode. neon project moves rust code into dir native, so it is not inside the root directory of the project.

you can checkout my source here: https://github.com/vigcoin/neon or create a new neon project and edit it with vscode.

@calidion I did try briefly rls --cli on your repo and wasn't able to reproduce your error. Will try in IDE (Eclipse Corrosion) later.

Hi @calidion

I did try your project on Eclipse. You may extrapolate for VSC.

Using neon\native as the project's root works.

Using neon as the project root doesn't work - As there is no Cargo.toml in the root of the project, Eclipse does not recognize it as a rust project.

I believe this behaviour is as intended.

If it's not too big a problem you could try placing a Cargo.toml containing a [workspace] section in the root of your neon project.
