11. def findMatch[T, U](futures: TraversableOnce[Future[T]])(pf: PartialFunction[T, U])(implicit ec: ExecutionContext): Future[Option[U]]

    

    Variant of Future.find that applies a PartialFunction, if it's defined, rather than checking a predicate.

    Variant of Future.find that applies a PartialFunction, if it's defined, rather than checking a predicate. This allows type safe transformation of matched values.

    For example, if you wanted to find the first string that represented a non-negative integer:

    val nonNegativeIntRegex = """[0-9]+""".r
    val futures: immutable.Seq[Future[String]] = startComputation()
    
    val matchOptionFuture: Future[Option[Int]] = Futures.findMatch(futures) {
      case nonNegativeIntRegex(s) => s.toInt
    }

    (Types added for clarity where they would normally be inferred.)

    With Future.find, you'd need to use something more verbose instead:

    val matchOptionFuture: Future[Option[Int]] = Futures.find(futures) {
      case nonNegativeIntRegex(s) => true
      case _ => false
    }.map(_.toInt)

14. def immediate[T](f: ⇒ T): Future[T]

    

    Executes f immediately without an ExecutionContext.

    Executes f immediately without an ExecutionContext.

    Returns a successful future if f completes or a failed one if f throws an exception.

21. def safelyCall[T](f: ⇒ Future[T]): Future[T]

    

    Executes f immediately.

    Executes f immediately. Returns f's future (either successful or not) if f completes or a failed one if f throws an exception.
