template<class Alloc> explicit queue(const Alloc& a);
Effects: Initializes c with a.
template<class Alloc> queue(const container_type& cont, const Alloc& a);
Effects: Initializes c with cont as the first argument and a as the second argument.
template<class Alloc> queue(container_type&& cont, const Alloc& a);
Effects: Initializes c with std​::​move(cont) as the first argument and a as the second argument.
template<class Alloc> queue(const queue& q, const Alloc& a);
Effects: Initializes c with q.c as the first argument and a as the second argument.
template<class Alloc> queue(queue&& q, const Alloc& a);
Effects: Initializes c with std​::​move(q.c) as the first argument and a as the second argument.
template<class InputIterator, class Alloc> queue(InputIterator first, InputIterator last, const Alloc& alloc);
Effects: Initializes c with first as the first argument, last as the second argument, and alloc as the third argument.
template<container-compatible-range<T> R, class Alloc> queue(from_range_t, R&& rg, const Alloc& a);
Effects: Initializes c with ranges​::​to<Container>(std​::​forward<R>(rg), a).
