定义于头文件 <stop_token>
template < class T, class CallbackFn >
using stop_callback_for_t = T :: template callback_type < CallbackFn > ;
(C++26 起)

别名模板 stop_callback_for_t 用于获取类型 T 对应的停止回调类型。

注释

对于标准停止令牌类型和任何有效的 CallbackFn ，对应的 stop_callback_for_t 为：

  • 针对 std:: stop_token 的 std:: stop_callback 特化版本，
  • 针对 std :: inplace_stop_token 的 std :: inplace_stop_callback 特化版本，以及
  • 针对 std :: never_stop_token 的未指定类型（不包含可停止回调的注册与注销功能）。
