rocket::http::Status as oapi responder

[l4l]

It seems that rocket::http::Status does not implement OpenApiResponder, so that simple route will fail:

use rocket::http::Status;

#[get("/")]
fn func() -> Status { Status::Ok }

It's quite tricky, because the interface is not supposed to have access to the object itself, only type. As a temporary workaround l4l@9206ab2 may work, though I don't really think it's a good idea to merge it.

Maybe some wrapper should be considered for statuses? Procedural macros cannot properly determine whether the item is particular type or not in general, afaik, although they may emit warnings for a wrapper hinting.

I think that it is safe to assume that if a route return's type is a rocket::http::Status when everything goes as expected the returned status will be Status::Ok. If not, I think that implementing something like #[okapi(return_code = "404")] would be the best course of action, altough I do not have a clue if it would be hard doing so...

This has been fixed in 1740ebc.
Okapi now uses the "default" setting in OpenAPI: https://spec.openapis.org/oas/v3.0.0#fixed-fields-13

This is a screenshot of the example: https://github.com/GREsau/okapi/blob/master/examples/special-types/src/main.rs#L17
It also works with just the rocket::http::Status (or other combination you might expect, like Result<Json<()>, rocket::http::Status>)
The documentation for these endpoint might be a bit scarce, because there is not much info that can be displayed.
