Grouped/named routes feature request

[BartWillems]

I have a feature request for grouped/named routes.
This could be used to ask rocket for the routes(their paths, contenttype, request type, ...) with some identifier.
Or maybe it could be useful to set some guard on an entire group?

In my head it could look like this:

rocket::ignite()
    .mount("/api",
                routes![login],
                "api_routes"
               );

Json(rocket::routes("api_routes").unwrap());
// [
//    {
//        "path" : "/api/login",
//        "type" : "POST"
//    }
// ]

Also 👍 if it's possible to set the same RequestGuard to group. Assigning same RequestGuard to dozens of function getting old pretty quick.

I'm facing the same need, I'd like to add the same guard to an entire set of routes rather than to every route starting with a common path. I'm curious if anyone has an elegant workaround at this point.

If you simply want to ask Rocket for information on a set of routes, you can group them into a variable yourself:

let these_routes = routes![a, b, c, d];

for route in these_routes {
    // get info on routes
}

If you want to ask questions later, you can put a HashMap in managed state:

struct RouteMap(HashMap<&'static str, Vec<Route>>);

fn main() {
    let mut map = HashMap::new();
    let these_routes = routes![a, b, c, d];
    map.insert("these_routes", these_routes.clone());

    rocket.mount("/", these_routes).manage(RouteMap(map)).launch();
}

#[get("/")]
fn map(routes: State<RouteMap>) { .. }

You can, of course, wrap this into a more elegant API if you'll be using it often.

@ourhut If we implement #749, such a thing would be possible elegantly.

Because the initial request is possible outside of Rocket and the follow-up should be possible by solving another issue, I'm closing this out.
