std::experi...t::Variable(3)

💅 std::experi...t::Variable 💅

okay so bestie, welcome to the group chat — this page lives in the C++ Standard Libary manual (yes that's how it's spelled on the tin, don't come for me 🙈), and today's main character is std::experimental::reflect::Variable. it's a concept from the Reflection TS, and honestly? it's giving niche-but-iconic. let's get into it 🎀

---

✨ NAME ✨

std::experimental::reflect::Variable — like, literally std::experimental::reflect::Variable. that's the name. that's the vibe. periodt. 🫶

---

✨ Synopsis ✨

first things first, where does it even live:

Defined in header <experimental/reflect>

then the actual declaration, copy-pasted exactly because we do not mess with code:

template< class T >                              (reflection TS)
concept Variable = Typed<T> && /* see below */;

so it's a template over class T, it's tagged (reflection TS), and the concept is defined as Typed<T> && plus "/* see below */" — and yeah, the see below is doing a lot of heavy lifting there ngl 💀 scroll down, it's explained.

the actual tea: the Variable concept is satisfied if and only if T reflects a variable or a data member. that's the whole check. if your T is out here reflecting a variable or a data member, congrats, it's a Variable. if not… it's not. no cap. 🔥

✨ Example ✨

okay so the example section is… not there yet 😭 straight from the page:

This section is incomplete Reason: examples

so nobody has blessed us with examples yet. we're waiting. patiently. sort of. 🧚

✨ See also ✨

and the see-also section is also living its incomplete era:

This section is incomplete Reason: templatization

no cross-links for us yet bestie, it's a work in progress. 💜

✨ Category ✨

• Todo with reason

yes, the category is literally just "Todo with reason". relatable honestly. 💀

and that's the whole page, you're caught up!! 🦋

shoutout to http://cppreference.com, dated 2024.06.10, and the header/footer both said std::experi...t::Variable(3) — truncated like that, with the ..., and we respect the truncation. slay. 💖✨
