Function resolve 

Source 
pub fn resolve(result: Result<Response, Error>) -> Response
Expand description

Convert a handler result into a definite Response.

Useful in middleware that needs to observe both success and error paths before returning — e.g. attaching an X-Request-Id header to every response regardless of outcome.
