std::packaged_task<R(Args...)>::operator=
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 |
