| 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) |
