std::experimental::memory_alignment
From cppreference.com
< cpp | experimental | simd
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.
If the program adds specializations for std::memory_alignment or std::memory_alignment_v(since C++17), the behavior is undefined.

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) |
