1) Copy assignment operator is deleted, std::packaged_task is move-only. Note: C++11 does not specify const here, this is the defect 2067.
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

Exceptions

2)
noexcept specification:  
noexcept
