std::atomic<T>::operator=

T operator=( T desired ) noexcept;	(1)	(C++11 起)
T operator=( T desired ) volatile noexcept;	(2)	(C++11 起)
atomic& operator=( const atomic& ) = delete;	(3)	(C++11 起)
atomic& operator=( const atomic& ) volatile = delete;	(4)	(C++11 起)

1,2) 将 desired 原子地赋给原子变量。等价于 store(desired)。

重载 (2) 在参与重载决议且 std::atomic<T>::is_always_lock_free 是 false 时被弃用。

(C++20 起)
