Deduction guides(C++17)

 

packaged_task& operator=( const packaged_task& ) = delete;	(1)	(since C++11)
packaged_task& operator=( packaged_task&& rhs ) noexcept;	(2)	(since C++11)

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.

Parameters

rhs

-

the std::packaged_task to move from
