std::simd::__vec_builtin(3cxx)

💅 std::simd::__vec_builtin

okay bestie, gather round, because today we're talking about std::simd::__vec_builtin — a C++ concept from the libstdc++ manual, section 3cxx. yes it's a real thing, yes it's adorable, yes it's basically a vibe check for vectors. 🦋

---

✨ NAME ✨

std::simd::__vec_builtin — literally the name, that's the whole thing, she's that iconic 💅

---

🌸 SYNOPSIS 🌸

first things first, you gotta bring in the header, no cap:

#include <vec_ops.h>

🎀 Concept definition 🎀

here's the actual definition, copy it exactly bestie, don't freestyle on me:

template<typename _Tp>
concept std::simd::__vec_builtin =  __vec_builtin_of<_Tp, remove_cvref_t<decltype(declval<const _Tp>()[0])>>

look at her. so pretty. so precise. ✨

---

💖 Detailed Description 💖

so what does she do? she constrains to any vector builtin. that's it. that's the whole job. 🫶

think of it like this: you hand her a type, and she's like "mmkay but is this a vector builtin tho" and if the answer is yes she lets you through the velvet rope. main character energy, honestly. 👑

ngl, this is an internal-ish concept — the double underscore in the name is a little "i'm shy, don't @ me" signal, iykyk. 💀

generated automatically by Doxygen for libstdc++, straight from the source code. so nobody wrote this by hand — she said "not me being compiled into documentation" and here we are. 😭

---

💜 SEE ALSO ✨

not a single related page listed. she stands alone. independent queen, periodt. 💅

and that's the whole page bestie!! this doc came to you from libstdc++, generated by Doxygen from the source code, and the manpage header signed off as std::simd::__vec_builtin(3cxx) — section 3cxx of the manual, in case you need to cite her. go forth and constrain responsibly. 🌈⭐🎀
