std::packaged_task
 
template< class Function, class... Args >

void swap( packaged_task<Function(Args...)> &lhs,

           packaged_task<Function(Args...)> &rhs ) noexcept;
 (since C++11)

Specializes the std::swap algorithm for std::packaged_task. Exchanges the state of lhs with that of rhs. Effectively calls lhs.swap(rhs).
