std::constructible_from(3)

std::constructible_from(3) 💅✨

okay bestie, we are in the C++ Standard Libary and this page is about std::constructible_from, a concept that is lowkey doing the most important vibe check on types. It's giving main character energy: “can I build a T out of these Args...?” 🔥

🎀 NAME 🎀

std::constructible_from - std::constructible_from

✨ Synopsis ✨

This cutie is defined in header <concepts>, and here’s the exact synopsis with zero edits, bestie:

          Defined in header <concepts>
          template< class T, class... Args >

          concept constructible_from =
       (since C++20)

              std::destructible<T> && std::is_constructible_v<T, Args...>;

The constructible_from concept specifies that a variable of type T can be initialized with the given set of argument types Args.... That’s the whole assignment, and it ate. 💖
