Helper classes

formatter<std::chrono::weekday_indexed>

 

constexpr bool operator==(const std::chrono::weekday_indexed& x,                           const std::chrono::weekday_indexed& y) noexcept;		(since C++20)

Compares the two weekday_indexed x and y.

Return value

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

Example

Run this code

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

Output:

true
