Can not aceess custom file

[incker]

I want to select file path + tail + ".gz"

My shorten code:

let route  = warp::any()
    .map(move || path.clone())
    .and(warp::path::tail())
    .and_then(|path, tail| warp::fs::file("index.html").filter());

I receive an error:

65 |         .and_then(|path, tail| warp::fs::file("index.html").filter());
   |                                                             ^^^^^^ method cannot be called on `impl warp::filter::FilterClone` due to unsatisfied trait bounds

And this code:

let route3 = warp::any()
    .map(move || path.clone())
    .and(warp::path::tail())
    .and_then(|path, tail| async { warp::fs::file("index.html") });

Gives such error:

65 |         .and_then(|path, tail| async {warp::fs::file("index.html")});
   |          ^^^^^^^^ expected opaque type, found enum `Result`

How can I call warp::fs::file(path). with custom path, based on tail but ends on tail + ".gz"?
Thank you

Hi, yeah at the moment it's a shortcoming of the file filter, it has been raised on #526 as well, see also #171 (comment) for more info.
Thanks
