mdspan: Facilities For Multidimensional Arrays

The mdspan sub-package provides a set of classes and functions for manipulating multidimensional arrays.

The public header is

#include "arene/base/mdspan.hpp"

The Bazel target is

//:mdspan

Introduction

This package provides the following classes and functions for describing and viewing multidimensional array data, as backports of the corresponding facilities from C++23.

• arene::base::extents
• arene::base::dextents
• arene::base::layout_stride::mapping
• arene::base::layout_left::mapping
• arene::base::layout_right::mapping
• arene::base::default_accessor
• arene::base::mdspan

Extensions

This package provides the following type traits as extensions on the C++23 facilities.

• arene::base::is_accessor_policy_v
• arene::base::is_layout_mapping_v
• arene::base::is_layout_mapping_policy_v
