How to find the current URL in Iron?

Question

How can I find the current URL inside an action/function? I've not found anything related to this in the documentation.

Answer 1

The Iron homepage has this "hello world" example:

fn hello_world(_: &mut Request) -> IronResult<Response> {
    Ok(Response::with((status::Ok, "Hello World!")))
}

The only input to the function is a Request. The very first field on that struct is a Url:

url: Url

The requested URL.
