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>

 

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

比较二个 weekday_indexed x 与 y 。

!= 运算符从 operator== 合成。

返回值

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

示例

运行此代码

#include <iostream>
#include <chrono>
 
int main()
{
    constexpr auto wdi1 {std::chrono::Tuesday[2]};
    constexpr std::chrono::weekday_indexed wdi2 {std::chrono::weekday(2), 2};
    std::cout << std::boolalpha << (wdi1 == wdi2) << '\n';
}

输出：

true
