std::experimental::simd_size

template< class T, class Abi = simd_abi::compatible<T> >
struct simd_size;

(parallelism TS v2) | |
If T is a vectorizable type and is_abi_tag_v<Abi> is true, 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.
Helper variable template
template< class T, class Abi = simd_abi::compatible<T> >
constexpr std::size_t simd_size_v = simd_size<T, Abi>::value;

Member constants
value [static] |
the width of simd<T, Abi> (public static member constant) |
Member functions
operator std::size_t |
converts the object to std::size_t, returns value (public member function) |
operator() (C++14) |
returns value (public member function) |
