std::future::future(3)

💖 NAME 💖

std::future::future — std::future::future ✨ (yes bestie, the name section is literally the name twice, and honestly? iconic).

This page is from the C++ Standard Libary manual, section 3. We're talking constructors today, so grab your emotional support compiler 🎀.

✨ Synopsis ✨

Exact synopsis, no edits, fr fr:

future() noexcept;                      (1) (since C++11)
future( future&& other ) noexcept;      (2) (since C++11)
future( const future& other ) = delete; (3) (since C++11)

Constructs a std::future object. That's the whole assignment: construct the future, slay 💅.

• (1) — Default constructor. Constructs a std::future with no shared state. After construction, valid() == false. So it's valid-adjacent? No bestie, it's literally false — it's a future with no shared-state tea yet 🫖.
• (2) — Move constructor. Constructs a std::future with the shared state of other using move semantics. After construction, other.valid() == false. The shared state has been moved out of other, and other is left invalid 💨.
• (3) — std::future is not CopyConstructible. It's = delete, so copying is not the move, bestie — do not attempt 🙈.

🌸 Parameters 🌸

• other — another std::future to acquire shared state from. That's the only parameter, and it's giving "hand over the shared state" energy 🫶.
