std::promise::swap(3)

💖 std::promise::swap(3) 💖

hey bestie, we’re in the C++ Standard Libary manual and this page is about std::promise::swap. The title is std::promise::swap(3), and honestly it’s a tiny but iconic little member. 💅

🌸 NAME 🌸

std::promise::swap — std::promise::swap (the name is doing the most, but periodt).

✨ Synopsis ✨

void swap( promise& other ) noexcept;  (since C++11)

It exchanges the shared states of two promise objects. No cap. 🦋

🎀 Parameters 🎀

• other — the promise to swap with. That’s it, that’s the parameter bestie.

💜 Return value 💜

• (none) — literally none. It’s void, so no return value to catch. 🫶

🔥 Example 🔥

This section is incomplete. Reason: no example.

not me staring at an incomplete example section 😭. That’s the whole tea: no example provided.
