Flatten Scala Try

Question

Is there a simple way to flatten a collection of try\'s to give either a success of the try values, or just the failure? For example:

def map(l:List[Int]) =          


        

Answer 1

These are my 2cents:

def sequence[A, M[_] <: TraversableOnce[_]](in: M[Try[A]])
  (implicit cbf:CanBuildFrom[M[Try[A]], A, M[A]]): Try[M[A]] = {
    in.foldLeft(Try(cbf(in))) {
      (txs, tx) =>
        for {
          xs <- txs
          x <- tx.asInstanceOf[Try[A]]
        } yield {
          xs += x
        }
    }.map(_.result())
  }
