Feature description

It would be great if there was an automated way to include mod <module_name> in lib.rs (or the parent module's source file). This would reduce the need for manual edits when adding new modules to the project, improving the developer experience and preventing potential mistakes when forgetting to declare new modules.

RustRover has this function.

Hey 👋

Thanks for the suggestion. Something like that should be implemented in rust-analyzer, not rustaceanvim.

But if I understand correctly, what you're looking for is automatic addition of module imports when you confirm a completion suggestion?
That's possible, but depends on the completion plugin you're using. rustaceanvim doesn't implement any completion-related features, as those are not specific to Rust.

That's not what I meant

Here's a screenshot from RustRover

When I create bar.rs, the IDE will add mod bar in lib.rs (or main.rs if there only a bin crate) if I select the Attach to module option

That would have to be implemented in rust-analyzer and possibly whichever file tree/directory viewer plugin you're using.
But I don't know if there's an LSP spec for that.
