Overview

This PR adds a new name attribute to the route macro, so that user can specify a resource name, which by default is the name of handler function since #1178, and call HttpRequest.url_for on the name later.

Example:

#[get("/static", name = "static")]
async fn static_file() -> impl Responder {
    // ...
}

Why do you feel using the handler name is not sufficient? Doesn using raw identifiers r#static not work?

[stdrc]

Thanks for reminding me the r#static solution, but I think this PR is still usefull if we want some special characters in the resource name. BTW, it's just a counterpart to Flask's endpoint parameter of route decorator.

Could it be a unwrap_or_else?

@therealprof Ok, resolved

[robjtede]

I can usually rebase master branch into PRs in order to coordinate the merge but you must have that option disabled. I'm sorry but I'm going to have to ask you to rebase again because another PR just got merged that fixed CI.
