std::chrono::weekday_last
 
在标头 <chrono> 定义 
constexpr bool operator==( const std::chrono::weekday_last& x,
                           const std::chrono::weekday_last& y ) noexcept;
(C++20 起)

比较二个 weekday_last 值 x 与 y。

!= 运算符从 operator== 运算符合成。

返回值

x.weekday() == y.weekday()

示例

运行此代码
#include <chrono>
#include <iostream>
 
int main()
{
    constexpr auto wdl1{std::chrono::Tuesday[std::chrono::last]};
    constexpr std::chrono::weekday_last wdl2{std::chrono::weekday(2)};
    std::cout << std::boolalpha
              << (wdl1 == wdl2) << ' '
              << (wdl1 == std::chrono::Wednesday[std::chrono::last]) << '\n';
}

输出： 

true false
