(parallelism TS v2) | |
If T is a valid type for the second argument to copy_from, copy_to or the corresponding load constructors of simd or simd_mask, 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 >
constexpr bool is_simd_flag_type_v = is_simd_flag_type<T>::value;

Inherited from std::integral_constant
Member constants
value [static] |
true if T is a load/store flag tag 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) |

Example
Run this code
#include <experimental/simd>
#include <iostream>
int main()
{
namespace stdx = std::experimental;
std::cout << std::boolalpha
<< stdx::is_simd_flag_type_v<stdx::element_aligned_tag> << '\n'
<< stdx::is_simd_flag_type_v<int> << '\n';
}
Output:
true
false
