Defined in header <experimental/simd>
template< class T > struct is_abi_tag;		(parallelism TS v2)

If T is an ABI tag in the simd_abi namespace, 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_abi_tag_v = is_abi_tag<T>::value;		(parallelism TS v2)

Inherited from std::integral_constant

Member constants

value [static]

true if T is an ABI 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)

Member types

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

Example

Run this code

#include <experimental/simd>
 
static_assert(std::experimental::is_abi_tag_v<stdx::simd_abi::scalar>);
static_assert(!std::experimental::is_abi_tag_v<int>);
 
int main() {}
