Конвертировать ListBuffer из кортежей в карту кортежей

Question

Я пытаюсь преобразовать ListBuffer кортежей [(value1, value2)] в Map [value1 -> (value1, value2)]

var ListBuffer = ListBuffer[(Int, Boolean)]()
.... (filling the listBuffer from file)
var portsMap = Map[Int,(Int,Boolean)]

//that was i thought right to do in order to achieve the Map
 portsMap = portListBuffer.toMap{(port, bool) => [port, (port,bool)]}
