The compiler gave you the answer you need.

Your extern crate statements are inside a module, and use statements require absolute paths. That is, when you say use url::Url; inside the interactive_test module, what you are actually saying is "use url::Url which is defined in the root module", which it isn't.

What you need to do is prefix the path with self:: to tell it to look in the current module. You can also use super:: to access the parent module (if that ever comes up).

Personally, I get around this by putting all my extern crate statements in the root module, which also serves as a kind of program-wide list of external crates being used.
