STD::SIMD___VEC_BUILTIN_OF(3)

💖 std::simd::__vec_builtin_of 💖

okay bestie, welcome to the std::simd:..._builtin_of(3) page from the Library Functions Manual — yes that's the whole manual name, we're fancy here 🎀

---

✨ NAME ✨

std::simd::__vec_builtin_of — the concept that goes "is this a vector builtin tho?" 💅

---

🌸 SYNOPSIS 🌸

First thing's first, you gotta pull in the header:

#include <vec_ops.h>

🦋 Concept definition 🦋

okay so here's the whole thing, no cap, every character exactly as it lives:

template<typename _Tp, typename _ValueType, __simd_size_type _Width = sizeof(_Tp) / sizeof(_ValueType)>
concept __vec_builtin_of = !is_class_v<_Tp> && !is_pointer_v<_Tp> && !is_arithmetic_v<_Tp>
      && __vectorizable<_ValueType>
      && _Width >= 1 && sizeof(_Tp) / sizeof(_ValueType) == _Width
      && same_as<__vec_builtin_type_bytes<_ValueType, sizeof(_Tp)>, _Tp>
      && requires(_Tp& __v, _ValueType __x) { __v[0] = __x; }

she's a concept, she's got a default template argument, she's doing math with sizeof, it's giving icon status fr fr 🔥

🌈 Detailed Description 🌈

So what does this concept actually do? It constrains to any vector builtin with a given value type and an optional width. That's the vibe check: if your type is a vector builtin of that value type and that width, she says yes. Periodt. 👑

💀 lowkey reminder: this page is machine-generated for libstdc++, so if something looks cryptic, that's not you, that's just Doxygen being Doxygen.

and that's the whole page, bestie — written up by that automatic Doxygen pipeline for libstdc++, sitting pretty under the std::simd:..._builtin_of(3) title. ily, go write some vector builtins 💖🫶🌸
