19. def grouped[From]: Grouped[From]

    Create an Enumeratee that groups input using the given Iteratee.

    Create an Enumeratee that groups input using the given Iteratee.

    This will apply that Iteratee over and over, passing the result each time as the input for the target Iteratee, until EOF is reached. For example, let's say you had an Iteratee that took a stream of characters and parsed a single line:

    def takeLine = for {
      line <- Enumeratee.takeWhile[Char](_ != '\n') &>> Iteratee.getChunks
      _    <- Enumeratee.take(1) &>> Iteratee.ignore[Char]
    } yield line.mkString

    This could be used to build an Enumeratee that converts a stream of characters into a stream of lines:

    def asLines = Enumeratee.grouped(takeLine)

    Create an Enumeratee that transforms its input using the given function.

    Create an Enumeratee that transforms its input using the given function.

    An enumeratee that passes all input through until EOF is reached, redeeming the final iteratee with EOF as the left over input.

37. def recover[E](f: (Throwable, Input[E]) ⇒ Unit = (_: Throwable, _: Input[E]) => ())(implicit ec: ExecutionContext): Enumeratee[E, E]

    Create an Enumeratee that recovers an iteratee in Error state.

    Create an Enumeratee that recovers an iteratee in Error state.

    This will ignore the input that caused the iteratee's error state and use the previous state of the iteratee to handle the next input.

    Enumerator(0, 2, 4) &> Enumeratee.recover { (error, input) =>
      Logger.error(f"oops failure occured with input: $input", error)
