Hi,
i' trying to build a custom directive which completes a *Future *of *Either*.
However, the following only works if i omit the status code when completing
the *Right* case (i.e. *complete(result)* ).
def completeEither[A](successStatusCode: StatusCodes.Success, future: =>
Future[Either[RequestError, A]])(implicit m: ToResponseMarshaller[A]) =
onSuccess(future) {
case Right(result) =>
complete(successStatusCode -> result)
case Left(BadRequest(message)) =>
complete(StatusCodes.BadRequest -> message)
case Left(_) =>
complete(StatusCodes.InternalServerError)
}
The compile error i get is: *Type mismatch, expected:
ToResponseMarshallable, actual: (StatusCodes.Success, A)*
I understand what the error message means but not where it comes from.
Based on this post
<https://groups.google.com/forum/#!topic/akka-user/jUEJm6UVItk> and due to
the implicit parameter, i'd assume that it should work.
Could anyone explain what i'm doing wrong?
Thanks & regards
Constantin
