std::stop_token
std:: stop_token & operator = ( const std:: stop_token & other ) noexcept ;
(1) (自 C++20 起)
std:: stop_token & operator = ( std:: stop_token && other ) noexcept ;
(2) (自 C++20 起)

将关联的停止状态替换为 other 的停止状态。

1) 将 other 关联的停止状态复制赋值给 * this 。等价于 stop_token ( other ) . swap ( * this ) 。
2) 将 other 的关联停止状态移动赋值给 * this 。赋值后， * this 包含 other 先前的关联停止状态，而 other 不再具有关联停止状态。等价于 stop_token ( std :: move ( other ) ) . swap ( * this ) 。

参数

其他 - 用于共享或获取停止状态的另一个 stop_token 对象
