std::stop_source
friend bool operator == ( const stop_source & lhs, const stop_source & rhs ) noexcept ;
(自 C++20 起)

比较两个 stop_source 值。

此函数对普通的 非限定查找 或 限定查找 不可见，仅当 std::stop_source 作为参数的关联类时，才能通过 实参依赖查找 找到该函数。

!= 运算符由 operator== 合成而来。

参数

lhs, rhs - 要比较的 stop_source 对象

返回值

如果 lhs 和 rhs 具有相同的停止状态，或两者均无停止状态，则为 true ，否则为 false 。
