Defined in header <experimental/simd>
template< class T, class U = typename T::value_type > struct memory_alignment;		(parallelism TS v2)

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.

The behavior of a program that adds specializations for std::memory_alignment or std::memory_alignment_v (since C++17) is undefined.

Helper variable template

template< class T, class U = typename T::value_type > inline constexpr std::size_t memory_alignment_v = memory_alignment<T, U>::value;		(parallelism TS v2)

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)

Member types

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