/* --------------------------------------------------------------------------
   Backwards-compat (optional):
   If you still have legacy handlers with `(HttpRequest, web::Path<String>, web::Json<Value>)`,
   you can write tiny adapters in the resources/controllers to convert them to `ActionHandler`.
   Example adapter (put near usage, not necessarily here):

   fn adapt_legacy<F>(
       f: F
   ) -> ActionHandler
   where
       F: Fn(HttpRequest, String, Value) -> Pin<Box<dyn Future<Output = HttpResponse>>> + Copy + 'static
   {
       move |req, path, body| {
           // Example: join segments with "/" if needed by legacy code
           let joined = path.join("/");
           f(req, joined, body)
       }
   }
