How to move elements out of STL priority queue

Question

C++\'s STL priority queue have a void pop() method, and a const ref top() method. Thus, if you want to move elements out of the queue, you have to do something like this:

Answer 1

This is indeed a flaw in std::priority_queue. But you can easily extend it like this:

template <
    class T,
    class Container = std::vector,
    class Compare = std::less>
class priority_queue : public std::priority_queue {
public:
  T top_and_pop() {
    std::pop_heap(c.begin(), c.end(), comp);
    T value = std::move(c.back());
    c.pop_back();
    return value;
  }

protected:
  using std::priority_queue::c;
  using std::priority_queue::comp;
};
