LowPriorityFuturesImplicits

Low priority implicits to add withTimeout methods to scala.concurrent.Future.

You can dependency inject the ActorSystem as follows to create a Future that will timeout after a certain period of time:

class MyService @Inject()(piCalculator: PiCalculator)(implicit futures: Futures) {

  def calculateWithTimeout(timeoutDuration: FiniteDuration): Future[Int] = {
     piCalculator.rawCalculation().withTimeout(timeoutDuration)
  }
}

You should check for timeout by using scala.concurrent.Future.recover or scala.concurrent.Future.recoverWith and checking for scala.concurrent.TimeoutException:

val future = myService.calculateWithTimeout(100 millis).recover {
  case _: TimeoutException =>
    -1
}
