Defined in header <variant>
template <class... Types> void swap(variant<Types...>& lhs, variant<Types...>& rhs)		(since C++17)

Overloads the std::swap algorithm for std::variant. Effectively calls lhs.swap(rhs).

Parameters

lhs, rhs

-

variant objects whose values to swap

Return value

(none)

Exceptions

noexcept specification:  

noexcept(lhs.swap(rhs))
