std::experi...al::any::any(3)

okay bestie, welcome to the std::experi...al::any::any(3) page from the C++ Standard Libary — yes, that's the manual name in the header, spelling and all, and we're rolling with it 🎀. This is the std::experimental::any::any constructor page, and it's giving overload family main character energy.

💖 NAME 💖

• std::experimental::any::any — std::experimental::any::any

ngl, the NAME line is literally the same name twice, and honestly? iconic. 💅

✨ Synopsis ✨

any() noexcept;               (1) (library fundamentals TS)
any( const any& other );      (2) (library fundamentals TS)
any( any&& other ) noexcept;  (3) (library fundamentals TS)
template<typename ValueType>  (4) (library fundamentals TS)
    any( ValueType&& value );

Constructs a new any object. That's the whole vibe check 🔥.

1. (1) — Constructs an empty object.
2. (2) — Copies the content of other into a new instance, so that any content is equivalent in both type and value to those of other prior to the constructor call, or empty if other is empty.
3. (3) — Moves the content of other into a new instance, so that any content is equivalent in both type and value to those of other prior to the constructor call, or empty if other is empty.
4. (4) — Constructs an object with initial content an object of type std::decay_t<ValueType>, direct-initialized from std::forward<ValueType>(value). If std::is_copy_constructible<std::decay_t<ValueType>>::value is false, the program is ill-formed. This overload participates in overload resolution only if std::decay_t<ValueType> is not the same type as any.

bestie, that ill-formed part is not a drill — if std::is_copy_constructible<std::decay_t<ValueType>>::value is false, the program is ill-formed, periodt. 💀

• ValueType — contained value type

🌸 Type requirements 🌸

• std::decay_t<ValueType> must meet the requirements of CopyConstructible.

🦋 Parameters 🦋

• other — another any object to copy or move from
• value — value to initialize the contained value with

💜 Exceptions 💜

• 2, 4 — Throws any exception thrown by the constructor of the contained type.
