Type Traits

xsimd provides a few type traits to interact with scalar and batch types in an uniform manner.

Combined traits:

batch_traits

batch types and proprties

Type check:

`is_batch`	batch type detection
`is_batch_bool`	mask batch type detection
`is_batch_complex`	complex batch type detection

Type access:

`scalar_type`	batch element type
`mask_type`	batch mask type

template<class T> struct batch_traits

#include <xsimd_traits.hpp>

type traits that provide information about a batch or scalar type.

template<class T> struct is_batch : public std::integral_constant<bool, batch_traits<T>::is_batch>

#include <xsimd_traits.hpp>

type traits that inherits from std::true_type for batch<...> types and from std::false_type otherwise.

template<class T> struct is_batch_bool : public std::integral_constant<bool, batch_traits<T>::is_batch_bool>

#include <xsimd_traits.hpp>

type traits that inherits from std::true_type for batch_bool<...> types and from std::false_type otherwise.

template<class T> struct is_any_batch : public std::integral_constant<bool, batch_traits<T>::is_any_batch>

#include <xsimd_traits.hpp>

type traits that inherits from std::true_type for batch<...> or batch_bool<…> types and from std::false_type otherwise.

template<class T> struct is_batch_complex : public std::integral_constant<bool, batch_traits<T>::is_batch && batch_traits<T>::is_complex>

#include <xsimd_traits.hpp>

type traits that inherits from std::true_type for batch<std::complex<...>> types and from std::false_type otherwise.

template<class T> struct scalar_type

#include <xsimd_traits.hpp>

type traits whose type field is set to T::value_type if is_batch<T>::value and to T otherwise.

template<class T> struct mask_type

#include <xsimd_traits.hpp>

type traits whose type field is set to T::value_type if is_batch_bool<T>::value and to bool otherwise.
