packaged_task& operator=( packaged_task&& rhs ) noexcept;

1) Copy assignment operator is deleted, std::packaged_task is move-only.
2) Releases the shared state, if any, destroys the previously-held task, and moves the shared state and the task owned by rhs into *this. rhs is left without a shared state and with a moved-from task.


rhs - the std::packaged_task to move from
