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

< cpp‎ | experimental‎ | simd

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

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

a type to check

Helper variable template

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

Inherited from std::integral_constant

Member constants

value

[static]

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

Member functions

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

Member types

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

Example

#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
