Scala - Traversing a ByteString Until Empty

Vote count:

Is there a more concise and/or performant way to traverse the message than what I have here?

   import akka.util.ByteString

   def nextValue(message: ByteString): (ByteString, ByteString)

   def processFields(message: ByteString): Unit = nextValue(message) match {

          case (_, Empty) => // Complete Parsing

          case (value, rest) =>
            // Do work with value

            // loop
            processFields(rest, fieldMap.tail)
       }
