Attaching Cargo projects
When working with a complicated project structure, you can add a particular directory containing a Rust package/workspace as a Cargo project and configure the project model for it separately.

Alternatively, right-click the Cargo.toml file in the project tree and select Attach Cargo Project from the context menu.
If there are some Cargo projects loaded already, open the Cargo tool window () and click the
icon in to attach the project:
