std::experimental::is_simd_flag_type - cppreference.com (original) (raw)

| | | | | ------------------------------------------------- | | ------------------- | | template< class T > struct is_simd_flag_type; | | (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.

[edit] Helper variable template

| template< class T > constexpr bool is_simd_flag_type_v = is_simd_flag_type<T>::value; | | (parallelism TS v2) | | ----------------------------------------------------------------------------------------------- | | ------------------- |

Inherited from std::integral_constant

Member constants

| | true if T is a load/store flag tag type, false otherwise (public static member constant) | | ------------------------------------------------------------------------------------------- |

Member functions

| | converts the object to bool, returns value (public member function) | | ---------------------------------------------------------------------- | | | returns value (public member function) |
