std::experi..._mask::size(3)

okay bestie, welcome to the std::experi..._mask::size(3) page from the C++ Standard Libary manual. The main character is std::experimental::simd_mask::size, and she’s here to hand you the width of simd_mask<T, Abi> with zero drama. 💅✨

🌸 NAME 🌸

• std::experimental::simd_mask::size - std::experimental::simd_mask::size

Yes, the NAME section is mirroring the same name twice — we love a consistent queen. 👑

✨ Synopsis ✨

Here’s the signature in all its static constexpr + noexcept glory:

static constexpr size_t size() noexcept;  (parallelism TS v2)

Returns the width (the number of values) of simd_mask<T, Abi>. That’s literally the whole job, and she ate. 💖

🦋 Example 🦋

The actual output depends on target and compiler flags. So don’t panic if your terminal serves different numbers — that’s just the target/compiler-flags situation, fr fr.

// Run this code

#include <experimental/simd>
#include <iostream>
namespace stdx = std::experimental;

int main()
{
    stdx::native_simd_mask<int> a { true };
    std::cout << a.size() << '\n';
    std::cout << popcount(a) << '\n';
}

🍓 Possible output: 🍓
