std::swap(std::deque) – std::swap(std::deque)

Synopsis

template <class T, class Alloc>

void swap(deque<T, Alloc> &lhs, (until C++ 17)

                                    deque<T, Alloc> &rhs);

template <class T, class Alloc>

void swap(deque<T, Alloc> &lhs, (since C++ 17)

                                    deque<T, Alloc> &rhs) noexcept(/* see below */);

Return value

(none)

Complexity
