Resource Regex Cause Panic

Question

1. This code is an attempt to replace a service that already works in production, written in java, with one written in rust.
2. This service will serve as a sidecar proxy for a redis cluster, exposing an api rest. It needs to maintain compatibility with the current api.

The Route is:

"/api/keys/{path:*}" 

In path we can put de name of the key for redis, and can contain any format below:

/api/keys/users/41728391
/api/keys/users/1000/followers
/api/keys/users/{1234}/data

this is my attempt

 HttpServer::new(move || App::new()
        .data(redis_config)
        .service(
            web::resource("/set/{path:*}").route(web::put().to(set_key))
        ) ).bind(("127.0.0.1", 8080))?
        .run()
        .await

I tried like this too:

#[get("/set/{path:*}")]...

But in two cases i get this error:

  .service(web::resource("/set/{path:*}").route(web::put().to(path_regex)))
   |                                                                         ^^^^^^^^^^ the trait `Factory<_, _, _>` is not implemented for `path_regex`
