All methods are inherited from the Iterator class. See the Iterator reference for documentation.

Example

var iterator = ArrayIterator([1, 2, 3]);
var combined_iterators = EnumerateIterator(iterator).for_each((pair) -> {
  println("Left: " + to_string(pair.left) + " Right: " + to_string(pair.right));
});
// "Left: 0, Right: 1"
// "Left: 1, Right: 2"
// "Left: 2, Right: 3"
