Transitional code to enhance Play 2.1 library so that Scala Futures have the await() function that Play 2.0 Promises had (until I can refactor).

transitional.scala

import scala.concurrent.Future
import scala.concurrent.duration._
import play.api.libs.concurrent.Execution.Implicits._

object WebServicesUtil {
  
  import scala.language.{implicitConversions, postfixOps}

  /** TRANSITIONAL: Simulate Play 2.0 await() for a Future, until code
    * is refactored.
    */
  class TransitionalFuture[+T](val future: Future[T]) {

    class NotWaiting[+A](future: Future[A]) {
      import scala.concurrent.Await

      def fold[B](onError: (Throwable) => B, onSuccess: (A) => B): B = {
        try {
          onSuccess(Await.result(future, 30 seconds))
        }
        catch {
          case e: Throwable => onError(e)
        }
      }

      def get: A = Await.result(future, 30 seconds)
    }

    def await: NotWaiting[T] = new NotWaiting(future)
  }
}
