std::error_...operatorbool(3)

💖 std::error_code::operatorbool 💖

okay so this is the std::error_code::operatorbool page from the C++ Standard Libary manual, section (3) — yes bestie, that exact manual name, typo and all, no cap. 🎀

🌸 NAME 🌸

std::error_code::operatorbool - std::error_code::operatorbool

✨ Synopsis ✨

the signature is literally this, and it’s been iconic since C++11:

explicit operator bool() const noexcept;  (since C++11)

Checks if the error code value is valid, i.e. non-zero.

🌈 Parameters 🌈

• (none) — literally no parameters, not a single one, periodt. 💅

🔥 Return value 🔥

• false if value() == 0
• true otherwise

🦋 Notes 🦋

okay so this is the part where we get real. Although this operator is often used as a convenient shorthand to check if any error was returned, as in:

if (ec) { /* handle error */ }

such use is not robust: some error codes, for example, HTTP status code 200, may indicate success as well. so like, vibe check before you assume error, okay? that’s the whole caveat, fr fr. 🫶
