std::experi...::simd_mask(3)

🌸 NAME 🌸

okay bestie, welcome to std::experimental::simd_mask — aka the std::experi...::simd_mask(3) page from the C++ Standard Libary manual. it’s giving data-parallel bool realness 💅

---

✨ Synopsis ✨

Defined in header <experimental/simd>:

template< class T, class Abi = simd_abi::compatible<T> >
(parallelism TS v2)
   class simd_mask;

the class template simd_mask is a data-parallel type with the element type bool. the width of a given simd_mask instantiation is a constant expression, determined by the template parameters. specifically, simd_mask<T, Abi>::size() is always simd<T, Abi>::size(). periodt. ✨

---

💖 Template parameters 💖

• T — the element type simd_mask applies on
• Abi — the ABI type simd_mask applies on

🧚 Helper alias templates 🧚

• template< class T, int N > using fixed_size_simd_mask — definition: simd_mask<T, simd_abi::fixed_size<N>>
• template< class T > using native_simd_mask — definition: simd_mask<T, simd_abi::native<T>>

---

🎀 Member types 🎀

• value_type — bool
• reference — implementation-defined
• simd_type — simd<T, Abi>
• abi_type — Abi

---

🦋 Member functions 🦋

• constructor — constructs a simd_mask object (parallelism TS v2) (public member function)
• copy_from — loads simd_mask elements from contiguous memory (parallelism TS v2) (public member function)
• copy_to — stores simd_mask elements to contiguous memory (parallelism TS v2) (public member function)
• operator[] — accesses specified element (parallelism TS v2) (public member function)
• operator! — negates each element (parallelism TS v2) (public member function)
• size — returns the width / number of elements [static] (parallelism TS v2) (public static member function)

---

🌈 Non-member functions 🌈

• operator&&, operator|| — element-wise logic operators (function) (parallelism TS v2)
• operator&, operator|, operator^ — element-wise bitwise operators (function) (parallelism TS v2)
• operator&=, operator|=, operator^= — element-wise compound operators (function) (parallelism TS v2)
• operator==, operator!= — element-wise relation operators (function) (parallelism TS v2)

---
