std::future::operator=(3)

💖 NAME 💖

okay so bestie, this is the <pink>std::future::operator=</pink> page — page (3), from the C++ Standard Libary manual — and it’s literally all about assigning one std::future to another. slay. ✨

🦋 Synopsis 🦋

future& operator=( future&& other ) noexcept;      (1) (since C++11)
future& operator=( const future& other ) = delete; (2) (since C++11)

Assigns the contents of another future object. yes bestie, that’s the whole assignment vibe. 💅

1. Number 1, the move-assign era — releases any shared state and move-assigns the contents of other to *this. After the assignment, other.valid() == false and this->valid() will yield the same value as other.valid() before the assignment. iconic behavior, honestly. 🎀
2. Number 2, the deleted copy-assign one — std::future is not CopyAssignable. like, not even a little bit. 💀

bestie, do not try to copy-assign a std::future — that one is = delete, periodt. 🙈

🌸 Parameters 🌸

• other — a std::future that will transfer state to *this. she’s giving main character energy and handing over the state. 🦋

🎀 Return value 🎀

*this

that’s it. that’s the return. no cap. ✨

that’s the whole vibe, bestie 💅 — this one’s from cppreference.com, dated/versioned 2024.06.10. mwah 🫶
