cancelRejections

§Signature

§Description

Adds a TransformationRejection cancelling all rejections created by the inner route for which the condition argument function returns true.

See also cancelRejection, for canceling a specific rejection.

Read Rejections to learn more about rejections.

For more advanced handling of rejections refer to the handleRejections directive which provides a nicer DSL for building rejection handlers.

§Example

def isMethodRejection: Rejection => Boolean = {
  case MethodRejection(_) => true
  case _                  => false
}
 
val route =
  cancelRejections(isMethodRejection) {
    post {
      complete("Result")
    }
  }
 
// tests:
Get("/") ~> route ~> check {
  rejections shouldEqual Nil
  handled shouldEqual false
}
