mapRouteResultWith
Description
Changes the message the inner route sends to the responder.
The mapRouteResult
directive is used as a building block for Custom Directives to transform the RouteResult coming back from the inner route. It’s similar to the mapRouteResult directive but returning a Future
instead of a result immediately, which may be useful for longer running transformations.
See Result Transformation Directives for similar directives.
Example
- Scala
-
case object MyCustomRejection extends Rejection val rejectRejections = // not particularly useful directive mapRouteResultWith { case Rejected(_) => Future(Rejected(List(AuthorizationFailedRejection))) case res => Future(res) } val route = rejectRejections { reject(MyCustomRejection) } // tests: Get("/") ~> route ~> check { rejection shouldEqual AuthorizationFailedRejection }
