std::experi...::simd_size(3)

okay bestie, welcome to the std::experi...::simd_size(3) page from the C++ Standard Libary manual 💖 this one is all about a cute little trait that tells you how wide a simd thing would be. no cap, every detail matters, so here we go 🫶

💅 NAME 💅

std::experimental::simd_size — std::experimental::simd_size

✨ Synopsis ✨

Defined in header <experimental/simd>
template< class T, class Abi = simd_abi::compatible<T> >
(parallelism TS v2)
struct simd_size;

If T is a vectorizable type and is_abi_tag_v<Abi> is true, it provides the member constant value equal to the width (number of elements) of simd<T, Abi>, irrespective of whether simd<T, Abi> is supported or not. For any other types T and Abi, there is no member value.

If the program adds specializations for std::simd_size or std::simd_size_v (since C++17), the behavior is undefined. so like… don't do that, bestie 😭

🎀 Member constants 🎀

• value — the width of simd<T, Abi>; [static] (public static member constant)

🦋 Member functions 🦋

• operator std::size_t — converts the object to std::size_t, returns value; public member function
• operator() — returns value; (C++14) public member function

🌸 Member types 🌸

• value_type → std::size_t
• type → std::integral_constant<std::size_t, value>
