NAME¶

std::experimental::is_simd,std::experimental::is_simd_mask - std::experimental::is_simd,std::experimental::is_simd_mask

Synopsis¶

Defined in header <experimental/simd>
template< class T > (1) (parallelism TS v2)
struct is_simd;
template< class T > (2) (parallelism TS v2)
struct is_simd_mask;

1) If T is a specialization of the simd class template, provides the member constant
value equal true. For any other type, value is false.
2) If T is a specialization of the simd_mask class template, provides the member
constant value equal true. For any other type, value is false.

Template parameters¶

T - a type to check

Helper variable template

template< class T > (parallelism TS v2)
inline constexpr bool is_simd_v = is_simd<T>::value;
template< class T > (parallelism TS v2)
inline constexpr bool is_simd_mask_v = is_simd_mask<T>::value;

Inherited from std::integral_constant

Member constants¶

value true if T is a simd/simd_mask type , false otherwise
[static] (public static member constant)

Member functions¶

operator bool converts the object to bool, returns value
(public member function)
operator() returns value
(C++14) (public member function)

Member types¶

Type Definition
value_type bool
type std::integral_constant<bool, value>

Example¶

// Run this code

#include <experimental/simd>
#include <iostream>

int main()
{
namespace stdx = std::experimental;
std::cout
<< std::boolalpha
<< stdx::is_simd_v<stdx::simd<float>> << '\n';
<< stdx::is_simd_v<int> << '\n';
<< stdx::is_simd_mask_v<stdx::simd_mask<float>> << '\n';
<< stdx::is_simd_mask_v<int> << '\n';
}

Output:¶

true
false
true
false
