PriorityQueueIterator

Cursor produced by PriorityQueue.iterator(). Yields elements in ascending order under the active comparator). Iteration is destructive-free: it drains into a snapshot first, so the queue can be mutated while the cursor is alive.

public class PriorityQueueIterator<T>: Iterator<T>

next

Returns the next element, or None if exhausted.

public fun next(): Option<T>
