boost::simd::preferred_alignment< T, Cardinal > Struct Template Reference

## Description

### template<typename T, std::size_t Cardinal = 0ULL> struct boost::simd::preferred_alignment< T, Cardinal >

Computes the preferred alignment for any type T vectorized with a given cardinal Cardinal.

This alignment is computed by the following formula:

• if T is Vectorizable, uses the alignment of a pack<T,Cardinal>
• if T is Vectorized, uses T::alignment directly
• if T is not Vectorizable, uses either the preferred alignment of its underlying value type (as computed by value_of) or its own natural alignment (as computed by alignof)

If Cardinal is unspecified, all computations are performed by assuming th default cardinal of current architecture Vectorized types is used.

Template Parameters
 T Type of data to be allocated Cardinal Cardinal of the pack to be used in the allocated memory.
