Hovering Over Items Doesn't Work in Nested Crates

[HTGAzureX1212]

I have a project with file structure like this:

The problem is that when I hover over definitions of Rust source files in the root src folder (not the one in lightsaber_bootlaoder), it works as expected.

For some unknown reason, when I hover over definitions of Rust source files in the src folder in lightsaber_bootloader, no information popped up. It works at a bare minimum in main.rs in that folder:

And everything else, straight up doesn't work.

I assume you don't use a cargo workspace. Rust-analyzer runs cargo metadata in the project root. Because lightsaber_bootloader is not part of the workspace, cargo metadata will ignore it and thus rust-analyzer won't know about it either. You can set "rust-analyzer.linkedProjects": ["lightsaber_bootloader/Cargo.toml"] to also run cargo metadata for lightsaber_bootloader.

I am actually using workspaces

Nevermind I figured it out, I needed to have the module included ._.

Maybe we could show some kind of big warning banner in such cases, with a button to automatically insert the mod statement...

[HTGAzureX1212]

Yes, that's what I used to have when I was using IntelliJ Rust

We can emit an "unused" diagnostic spanning the whole file, like we do for code that's #[cfg]'d out.

@flodiebold dupe of #6377?

[flodiebold]

Yeah, I'd say so.
