  1. def retry[T](attempt: () ⇒ Future[T], attempts: Int, delay: FiniteDuration)(implicit ec: ExecutionContext, scheduler: Scheduler): Future[T]

    Given a function from Unit to Future, returns an internally retrying Future The first attempt will be made immediately, each subsequent attempt will be made after 'delay' A scheduler (eg context.system.scheduler) must be provided to delay each retry If attempts are exhausted the returned future is simply the result of invoking attempt.

    Given a function from Unit to Future, returns an internally retrying Future The first attempt will be made immediately, each subsequent attempt will be made after 'delay' A scheduler (eg context.system.scheduler) must be provided to delay each retry If attempts are exhausted the returned future is simply the result of invoking attempt. Note that the attempt function will be invoked on the given execution context for subsequent tries and therefore must be thread safe (not touch unsafe mutable state).

    Example usage:

    protected val sendAndReceive: HttpRequest => Future[HttpResponse]
private val sendReceiveRetry: HttpRequest => Future[HttpResponse] = (req: HttpRequest) => retry[HttpResponse](
  attempt = () => sendAndReceive(req),
  attempts = 10,
  delay = 2 seconds,
  scheduler = context.system.scheduler
)
