template<typename T, std::size_t N>
void swap(haz::SharedQueue<T, N> const& lhs, haz::SharedQueue<T, N> const& rhs) noexcept(/* see below */);

Specialize the std::swap algorithm for haz::SharedQueue. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs).

(none)

Constant.

Output:

Contents of A:
0, 1, 2, 3,
Contents of B:
4, 5, 6,
Swap
Contents of A:
4, 5, 6,
Contents of B:
0, 1, 2, 3,
