The files cursor isnt changed. Once these are in place, the entire module tree is built and looks like this: Each module can refer to any other module in the tree much like you can use the filesystem: absolute paths begin with crate (which is like /), and relative paths begin with self (.) The idea is to keep the coupling between my own logic and the libraries low so the hassle of migrating from one third party crate to another is kept to a minimum when for instance changing the database-ORM library or API framework.
