Description

Issue by kubukoz Tuesday Mar 01, 2016 at 10:32 GMT Originally opened as https://github.com/akka/akka/issues/19930

Enable calls like

case class UserId(i: Int)

"id".as[Int].as(i => UserId(i))

Contributor guide

Research direction
Look at the existing Unmarshaller implementations in Akka HTTP, especially how `as` method works on String Unmarshaller. Then propose a new method that takes a function to transform the result, e.g., `map` on Unmarshaller. Consider adding an extension method or modifying the existing API.
