{unknown} type information for url::Url::parse

[drguildo]

With version 2.1.1 of the url crate and the following code:

fn main() {
    use url::Url;
    let issue_list_url =
        Url::parse("https://github.com/rust-lang/rust/issues?labels=E-easy&state=open");
}

when I hover over Url::parse I get {unknown}.

Does it work if you move the use statement outside the function?

[drguildo]

@flodiebold Yes. If I move the use to the top level I get the expected type information and documentation.

Then this is a duplicate of #1165.
