    template< class T >
constexpr void swap( std::experimental::propagate_const<T>& lhs,
                     std::experimental::propagate_const<T>& rhs ) noexcept(/* see below */);
    		(library fundamentals TS v2)

    Specializes the swap algorithm for std::experimental::propagate_const. Swaps the pointers of lhs and rhs. Equivalent to lhs.swap(rhs).

    This overload participates in overload resolution only if std::is_swappable_v<T> is true.

    		(library fundamentals TS v3)

    Parameters

    lhs, rhs - propagate_consts whose contents to swap

    Return value

    (none)

    Exceptions

    noexcept specification:  
    noexcept(noexcept(lhs.swap(rhs)))

    Complexity

    Constant.
