定義於標頭檔案 <stop_token>
template< class T, class CallbackFn > using stop_callback_for_t = T::template callback_type<CallbackFn>;		(C++26 起)

別名模板 stop_callback_for_t 用於獲取型別 T 的停止回撥型別。

注意

對於標準停止令牌型別和任何有效的 CallbackFn，相應的 stop_callback_for_t 是：

• std::stop_callback 對於 std::stop_token 的特化，
• std::inplace_stop_callback 對於 std::inplace_stop_token 的特化，以及
• 對於 std::never_stop_token，是不支援停止回撥註冊和登出的未指定型別。
