Usage
/* Create an empty priority queue */let minQueue = PriorityQueue.make(Pervasives.compare); /* Add some items */minQueue->PriorityQueue.push(7);minQueue->PriorityQueue.push(5);minQueue->PriorityQueue.push(10); /* Remove the top item */Js.log(minQueue->PriorityQueue.pop); /* Returns Some(5) */ /* Return the top item (without removing it) */Js.log(minQueue->PriorityQueue.peek); /* Returns Some(7) */ /* Remove the top item, throwing Not_found if the queue is empty */Js.log(minQueue->PriorityQueue.popExn); /* Returns 7 */ /* Return the top item, throwing Not_found if the queue is empty */Js.log(minQueue->PriorityQueue.peekExn); /* Returns 10 */ /* Get the size of the queue */Js.log(minQueue->PriorityQueue.size); /* Returns 1 */ /* Populate a priority queue with an existing array */let minQueue = PriorityQueue.fromArray([|7, 5, 10|], Pervasives.compare); /* Set the top to be the max element */let maxQueue = PriorityQueue.make((a, b) => b - a);
