std::promise::operator=(3)

okay so welcome to std::promise::operator= from the C++ Standard Libary manual 💅 yes bestie, that's the vibe, let's get into it.

💅 NAME

The original NAME line is literally std::promise::operator= - std::promise::operator=, and honestly? no notes. 💅

✨ Synopsis ✨

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

Assigns the contents. that's the whole assignment agenda, no cap 🎀

1. Move assignment operator. First, abandons the shared state (as in ~promise()), then assigns the shared state of other as if by executing std::promise(std::move(other)).swap(*this). highkey iconic behavior 🔥
2. promise is not copy-assignable. periodt.

🚨 real talk: item 2 is not a suggestion — promise is not copy-assignable.

🎀 Parameters

• other — another promise to acquire the state from 🫶

🫶 Return value

*this — that's it, that's the return value, literally the main character returning itself ✨
