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

构造一个新的 stop_token 对象。

1) 构造一个空的 stop_token ，没有关联的停止状态。
2) 拷贝构造函数。构造一个 stop_token ，其关联的停止状态与 other 相同。
3) 移动构造函数。构造一个 stop_token ，其关联停止状态与 other 相同； other 将变为空状态。

参数

其他 - 用于构造此 stop_token 对象的另一个 stop_token 对象

后置条件

1) stop_possible() 与 stop_requested() 均为 false 。
2) * this 与 other 共享相同的关联停止状态且比较结果相等。
3) * this 具有 other 先前关联的停止状态，且 other. stop_possible ( ) 为 false 。
