Detailed Description

template<typename simd_t>
struct seqan3::simd::simd_traits< simd_t >

seqan3::simd::simd_traits is the trait class that provides uniform interface to the properties of simd_t types.

Template Parameters

simd_t

The simd type that satisfies seqan3::simd::simd_concept.

The class defines the following member variables and types:

• scalar_type - the underlying type of a simd vector
• length - the number of packed values in a simd vector
• max_length - the maximum number of packable values in a simd vector, if the underlying type would be [u]int8_t
• mask_type - the type returned by comparison operators
• swizzle_type - the type used to define how to swizzle a simd vector
• rebind - the type used to rebind a simd vector to another scalar_type
