26.6.5 Class template priority_queue [priority.queue]

26.6.5.4 priority_queue specialized algorithms [priqueue.special]

template <class T, class Container, class Compare>
  void swap(priority_queue<T, Container, Compare>& x,
            priority_queue<T, Container, Compare>& y) noexcept(noexcept(x.swap(y)));

Remarks: This function shall not participate in overload resolution unless is_swappable_v<Container> is true and is_swappable_v<Compare> is true.

Effects: As if by x.swap(y).
