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
.
If the program adds specializations for std::memory_alignment
or std::memory_alignment_v
(since C++17), the behavior is undefined.

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) |
