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

比较两个 weekday_indexed x 与 y。

!= 运算符从 operator== 运算符合成。

[编辑] 返回值

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

[编辑] 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);
}
