Detailed Description

template<typename scalar_t, size_t length>
struct seqan3::detail::builtin_simd< scalar_t, length >

A class that holds the type of a simd implementation called [vector extension] (https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html) (formerly known as "seqan simd" in seqan2).

Template Parameters

scalar_t	The underlying type of a simd vector
length	The number of packed values in a simd vector

seqan3::detail::builtin_simd is basically defined as:

template <typename scalar_t, size_t length>
struct builtin_simd
{
   using type [[gnu::vector_size(sizeof(scalar_t) * length)]] = scalar_t;
};

Attention: This class itself only delegates to a [vector extension] (https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html) type, which is offered by the compiler as a builtin type.
