std::experi...al::in_place(3)

🌸 NAME 🌸

Hiiii bestie! This is the std::experi...al::in_place(3) page from the C++ Standard Libary manual — yes, “Libary” is literally spelled like that up top, and we are respecting the typo, periodt. 💅

std::experimental::in_place — std::experimental::in_place (she’s self-titled and iconic 👑)

✨ Synopsis ✨

Defined in header <experimental/optional>:

constexpr in_place_t in_place{};

That declaration is the (library fundamentals TS) version, bestie. Keep it exact — no cap. 🫶

Okay so std::experimental::in_place is a constant of type std::experimental::in_place_t that is used to disambiguate the overloads of constructors and member functions that take arguments (possibly a parameter pack) for in-place construction of some value. It’s giving “tiny tag, huge job” energy. 💖
