If is_simd_mask_v<T> is true and U is bool, or if is_simd_v<T> is true and U is a vectorizable type, provides the member constant value equal to the minimum alignment of a pointer passed to a load constructor, copy_from function, or copy_to function. For any other types T and U, there is no member value.
If the program adds specializations for std::memory_alignment or std::memory_alignment_v(since C++17), the behavior is undefined.
Helper variable template
| template< class T, class U = typename T::value_type > constexpr std::size_t memory_alignment_v = memory_alignment<T, U>::value; |

Inherited from std::integral_constant
Member constants
| value [static] |
the minimum alignment of a pointer passed to a load constructor, copy_from function, or copy_to function (public static member constant) |
Member functions
| operator std::size_t |
converts the object to std::size_t, returns value (public member function) |
| operator() (C++14) |
returns value (public member function) |
