std::chrono::weekday_indexed

成员函数

weekday_indexed::weekday_indexed

weekday_indexed::weekday

weekday_indexed::index

weekday_indexed::ok

非成员函数

operator==

operator<<

辅助类

formatter<std::chrono::weekday_indexed>

hash<std::chrono::weekday_indexed> (C++26)

 

定义在头文件 <chrono> 中
constexpr bool operator==( const std::chrono::weekday_indexed& x,                            const std::chrono::weekday_indexed& y ) noexcept;		(自 C++20 起)

比较两个 weekday_indexed x 和 y.

!= 运算符是 从 operator== 合成 的。

返回值

x.weekday() == y.weekday() && x.index() == y.index()

示例

运行此代码

#include <chrono>
 
int main()
{
    constexpr std::chrono::weekday_indexed wdi1{std::chrono::Wednesday[2]};
    constexpr std::chrono::weekday_indexed wdi2{std::chrono::weekday(3), 2};
    static_assert(wdi1 == wdi2);
}
