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

 

constexpr std::chrono::year year() const noexcept;	(1)	(since C++20)
constexpr std::chrono::month month() const noexcept;	(2)	(since C++20)

Retrieves the year and month values stored in this year_month object.

Return value

1) Returns the stored std::chrono::year value.

2) Returns the stored std::chrono::month value.

Example

Run this code

#include <chrono>
#include <iostream>
 
int main()
{
    std::cout << std::boolalpha;

    constexpr auto ym{std::chrono::year(2021)/std::chrono::July};  
    std::cout << (ym.year() == std::chrono::year(2021)) << ' ';
    std::cout << (ym.month() == std::chrono::month(7)) << '\n';
}

Output:

true true
