  13. def future[A](f: ⇒ Future[CallbackTo[A]])(implicit ec: ExecutionContext): Callback

    Wraps a Future so that it is repeatable, and so that its inner callback is run when the future completes.

    Wraps a Future so that it is repeatable, and so that its inner callback is run when the future completes.

    The result is discarded. To retain it, use CallbackTo.future instead.

    Because the Future is discarded, when an exception causes it to fail, the exception is re-thrown. If you want the exception to be ignored or handled differently, use CallbackTo.future instead and then .void to discard the future and turn the result into a Callback.

    WARNING: Futures are scheduled to run as soon as they're created. Ensure that the argument you provide creates a new Future; don't reference an existing one.
