def reject: StandardRoute
def reject(rejections: Rejection*): StandardRoute


Explicitly rejects the request optionally using the given rejection(s).

reject uses the given rejection instances (which might be the empty Seq) to construct a RouteRoute which simply calls requestContext.reject. See the chapter on Rejections for more information on what this means.

After the request has been rejected at the respective point it will continue to flow through the routing structure in the search for a route that is able to complete it.

The explicit reject directive is used mostly when building Custom Directives, e.g. inside of a flatMap modifier for “filtering out” certain cases.

    path("a") {
    path("b") {
      // trigger a ValidationRejection explicitly
      // rather than through the `validate` directive

// tests:
Get("/a") ~> route ~> check {
  responseAs[String] shouldEqual "foo"

Get("/b") ~> route ~> check {
  rejection shouldEqual ValidationRejection("Restricted!")
