std::experi...~scope_fail(3)

okay so bestie, this is the std::experi...~scope_fail(3) page from the C++ Standard Libary manual — yes, we are in the C++ corner of the group chat. It’s all about the destructor std::experimental::scope_fail::~scope_fail, and it’s short, sweet, and lowkey giving cleanup main character energy. 💅

💖 NAME 💖

std::experimental::scope_fail::~scope_fail — that’s the whole name, and then it literally repeats itself: std::experimental::scope_fail::~scope_fail. It’s giving “I said what I said” energy, and honestly? Iconic. ✨

✨ Synopsis ✨

~scope_fail() noexcept;  (library fundamentals TS v3)

So this destructor is noexcept. When it runs, it calls the exit function if the result of std::uncaught_exceptions() is greater than the counter of uncaught exceptions — typically on stack unwinding — and the scope_fail is active. Then it destroys the stored EF (if it is a function object) and any other non-static data members. Cleanup slay, fr fr. 🧹💅

🦋 Notes 🦋

Here’s the vibe check: whether the destructor is called on stack unwinding can be detected by the comparison of the result of std::uncaught_exceptions() and the counter of uncaught exceptions in the scope_fail. That’s literally the detection mechanism, no cap. 👀

• release — makes the scope_fail inactive (public member function). Obsessed with a clean exit? This is your girl. 🫶
