std::chrono...hrono::day)(3)

🎀 std::chrono::operator==,(std::chrono::day) 🎀

okay bestie, welcome to the C++ Standard Libary manual page for std::chrono::operator==,(std::chrono::day) 💖 the header is giving std::chrono...hrono::day)(3) energy, but the actual main character is comparing std::chrono::day values. no cap.

💅 NAME 💅

std::chrono::operator==,(std::chrono::day) — yep, that's the whole name, and it's literally the equality + spaceship comparison page for std::chrono::day. periodt ✨

✨ Synopsis ✨

Defined in header <chrono>.

constexpr bool operator==( const std::chrono::day& x,
                           const std::chrono::day& y ) noexcept;

(1) (since C++20)

constexpr std::strong_ordering operator<=>( const std::chrono::day& x,
                                            const std::chrono::day& y ) noexcept;

(2) (since C++20)

Compare the two std::chrono::day x and y 🫶

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively. slay 💅

🦋 Return value 🦋

1. unsigned(x) == unsigned(y)
2. unsigned(x) <=> unsigned(y)

🌸 Example 🌸

// Run this code

#include <chrono>
#include <iostream>

int main()
{
    constexpr std::chrono::day x{13}, y{31};
    static_assert(x != y);

    if constexpr (constexpr auto res = x <=> y; res < 0)
        std::cout << "x is less than y\n";
    else if constexpr (res > 0)
        std::cout << "x is greater than y\n";
    else
        std::cout << "x and y are equal\n";

    using namespace std::literals::chrono_literals;

    static_assert
    (
        (6d < 9d) && (6d == 6d) && (6d <= 9d) &&
        (9d > 6d) && (9d != 6d) && (9d >= 6d)
    );
}

⭐ Output ⭐

x is less than y
