std::chrono...onth_weekday(3)

🎀 NAME 🎀

std::chrono::year_month_weekday::year_month_weekday — std::chrono::year_month_weekday::year_month_weekday

okay so bestie, this is the constructor page for std::chrono::year_month_weekday, coming at you from the C++ Standard Libary manual, page std::chrono...onth_weekday(3). It’s literally the “build me a year_month_weekday object” page, and it has four constructors, all since C++20. 💅

✨ Synopsis ✨

The constructors are:

• (1) (since C++20)

year_month_weekday() = default;

• (2) (since C++20)

constexpr year_month_weekday( const std::chrono::year& y,
                              const std::chrono::month& m,
                              const std::chrono::weekday_indexed& wdi ) noexcept;

• (3) (since C++20)

constexpr year_month_weekday( const std::chrono::sys_days& dp ) noexcept;

• (4) (since C++20)

constexpr explicit year_month_weekday( const std::chrono::local_days& dp ) noexcept;

Constructs a year_month_weekday object. Let’s break the four flavors down, bestie:

1. (1) Default constructor leaves the fields uninitialized. No cap, that’s the whole caveat: it does not secretly fill them in for you 😭.
2. (2) Constructs a year_month_weekday object storing the year y, the month m, the weekday wdi.weekday() and the weekday index wdi.index().
3. (3) Constructs a year_month_weekday object corresponding to the date represented by dp. For any year_month_weekday object storing a valid date, converting it to sys_days and back yields the same value. This constructor defines an implicit conversion from sys_days to year_month_weekday.
4. (4) Constructs a year_month_weekday object corresponding to the date represented by dp. Equivalent to year_month_weekday(sys_days(dp.time_since_epoch())).

💜 Notes 💜

A year_month_weekday can also be created by combining one of the partial-date types std::chrono::year_month and std::chrono::month_weekday with the missing component (indexed weekday and year, respectively) using operator/. That’s the cute little calendar-builder move, iykyk 🎀.

bye bestie 🫶 this page came from http://cppreference.com, version/date 2024.06.10, and the page/manual name is std::chrono...onth_weekday(3). 💖
