std::layout_stride::mapping
Defined in header
<mdspan>
template< class Extents >
class layout_stride::mapping;
(since C++23)
class layout_stride::mapping;
The class template layout_stride::mapping controls how multidimensional indices are mapped with user-defined strides to a one-dimensional value representing the offset.
Every specialization of mapping is a LayoutMapping and a TriviallyCopyable type which satisfies regular.
The program is ill-formed if the size of the multidimensional index space Extents() is not representable as a value of type Extents::index_type when Extents::rank_dynamic() is 0.
