std::jthread
std:: jthread & operator = ( std:: jthread && other ) noexcept ;
(自 C++20 起)

如果 * this 仍关联运行中的线程（即 joinable ( ) == true ），则调用 request_stop ( ) 后接 join ( ) 。将 other 的状态赋予 * this ，并将 other 设置为默认构造状态。

在此次调用后， this - > get_id ( ) 等于调用前 other. get_id ( ) 的值，同时关联的停止状态也被转移，且 other 不再代表执行线程也不具有任何停止状态。

参数

其他 - 要分配给此 jthread 对象的另一个 jthread 对象

返回值

* this
