Struct gotham::router::route::matcher::AndRouteMatcher

pub struct AndRouteMatcher<T, U>
where
    T: RouteMatcher,
    U: RouteMatcher,
{ /* private fields */ }

Allows multiple RouteMatcher values to be combined when accessing a request.

Examples

  let methods = vec![Method::GET, Method::HEAD];
  let supported_media_types = vec![mime::APPLICATION_JSON];
  let method_matcher = MethodOnlyRouteMatcher::new(methods);
  let accept_matcher = AcceptHeaderRouteMatcher::new(supported_media_types);
  let matcher = AndRouteMatcher::new(method_matcher, accept_matcher);

  state.put(Method::GET);

  // Request that matches both requirements
  let mut headers = HeaderMap::new();
  headers.insert(ACCEPT, mime::APPLICATION_JSON.to_string().parse().unwrap());
  state.put(headers);
  assert!(matcher.is_match(&state).is_ok());

  // Request that fails method requirements
  state.put(Method::POST);
  assert!(matcher.is_match(&state).is_err());

  // Request that fails accept header
  state.put(Method::GET);
  let mut headers = HeaderMap::new();
  headers.insert(ACCEPT, mime::TEXT.to_string().parse().unwrap());
  state.put(headers);
  assert!(matcher.is_match(&state).is_err());
