Type Traits¶

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

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 xsimd::is_batch¶

#include <xsimd_traits.hpp>

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

Template Parameters

Inherits from false_type

template <class T>

struct xsimd::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 Parameters

Inherits from false_type

template <class T>

struct xsimd::is_batch_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 Parameters

Inherits from false_type

template <class T>

struct xsimd::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 Parameters

template <class T>

struct xsimd::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.

Template Parameters
