Example
- Scala
-
case object MyCustomRejection extends Rejection val rejectRejections = // not particularly useful directive mapRouteResultWithPF { case Rejected(_) => Future(Rejected(List(AuthorizationFailedRejection))) } val route = rejectRejections { reject(MyCustomRejection) } // tests: Get("/") ~> route ~> check { rejection shouldEqual AuthorizationFailedRejection }
