find first success.scala

  def findFirstSuccess[A, B](f: A => B)(iter: Iterator[A]): Option[B] = {
    var result: Option[B] = None
    iter.find { a: A =>
      Try {
        result = Option(f(a))
      }.isSuccess
    }
    result
  }

def collectFirstSuccess[A,B](it: Iterator[A], f:A =>B) = it.map({i => Try(f(i))}).collectFirst({case Success(i) => i})

yup thanks.

iter.map(x => Try(f(x))).collectFirst { case Success(y) => y }
