template< class... Types > void swap( tuple<Types...>& lhs, tuple<Types...>& rhs ) noexcept(/* see below */);		(since C++11)

Swaps the contents of lhs and rhs. Equivalent to lhs.swap(rhs).

This function does not participate in overload resolution unless std::is_swappable<Ti>::value is true for all i from 0 to sizeof...(Types).

(since C++17)

Parameters

lhs, rhs

-

tuples whose contents to swap

Return value

(none)

Exceptions

noexcept specification:  

noexcept(noexcept(lhs.swap(rhs)))
