23.6.4 Class template priority_queue [priority.queue]

23.6.4.2 Constructors [priqueue.cons]

constexpr priority_queue(const Compare& x, const Container& y);
constexpr priority_queue(const Compare& x, Container&& y);

Preconditions: x defines a strict weak ordering ([alg.sorting]).

Effects: Initializes comp with x and c with y (copy constructing or move constructing as appropriate); calls make_heap(c.begin(), c.end(), comp).

template<class InputIterator>
  constexpr priority_queue(InputIterator first, InputIterator last, const Compare& x = Compare());

Preconditions: x defines a strict weak ordering ([alg.sorting]).

Effects: Initializes c with first as the first argument and last as the second argument, and initializes comp with x; then calls make_heap(c.begin(), c.end(), comp).

template<class InputIterator>
  constexpr priority_queue(InputIterator first, InputIterator last, const Compare& x,
                           const Container& y);
template<class InputIterator>
  constexpr priority_queue(InputIterator first, InputIterator last, const Compare& x,
                           Container&& y);

Preconditions: x defines a strict weak ordering ([alg.sorting]).

Effects: Initializes comp with x and c with y (copy constructing or move constructing as appropriate); calls c.insert(c.end(), first, last); and finally calls make_heap(c.begin(), c.end(), comp).

template<container-compatible-range<T> R>
  constexpr priority_queue(from_range_t, R&& rg, const Compare& x = Compare());

Preconditions: x defines a strict weak ordering ([alg.sorting]).

Effects: Initializes comp with x and c with ranges::to<Container>(std::forward<R>(rg)) and finally calls make_heap(c.begin(), c.end(), comp).
