std::experi...y::operator=(3)

💖 std::experi...y::operator=(3) 💖

hey bestie, welcome to the std::experi...y::operator=(3) page from the C++ Standard Libary 💖 this is the assignment operator for std::experimental::any, and it's honestly giving main character energy ✨

---

💅 NAME 💅

std::experimental::any::operator= - std::experimental::any::operator=. That's the whole name, no cap, periodt 💅

---

✨ Synopsis ✨

          any& operator=( const any& rhs );      (1) (library fundamentals TS)
          any& operator=( any&& rhs ) noexcept;  (2) (library fundamentals TS)
          template< typename ValueType >         (3) (library fundamentals TS)
              any& operator=( ValueType&& rhs );

okay so the whole assignment vibe is: assigns contents to the contained value. That's the job, bestie. 🫶

1. Assigns by copying the state of rhs, as if by any(rhs).swap(*this). copy girl summer 💖
2. Assigns by moving the state of rhs, as if by any(std::move(rhs)).swap(*this). rhs is left in a valid but unspecified state after the assignment — so like, it's alive but not necessarily the same vibe, yk? 🦋
3. Assigns the type and value of rhs, as if by any(std::forward<ValueType>(rhs)).swap(*this). 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. no cap, those are the rules 🔥

---

🌸 Template parameters 🌸

• ValueType — contained value type. It's the contained value type, bestie, and that's the tea 🎀

---

🦋 Type requirements 🦋

• std::decay_t<ValueType> must meet the requirements of CopyConstructible. So it's giving "must be copy constructible" energy, and that's non-negotiable 💅

---

🎀 Parameters 🎀

• rhs — object whose contained value to assign. That's the object whose contained value you're assigning, fr fr.

---

⭐ Return value ⭐

*this — yes bestie, it returns *this and hands the vibe right back to you 💖

---

🔥 Exceptions 🔥

1,3) Throws bad_alloc or any exception thrown by the constructor of the contained type. If an exception is thrown, there are no effects (strong exception guarantee). So if it throws, it's like nothing happened — strong exception guarantee, iconic 😭👑
