Defined in header <mdspan>
template< class LayoutMapping > struct submdspan_mapping_result;		(since C++26)

Specializations of submdspan_mapping_result are result types returned by overloads of submdspan_mapping.

This class template has no base classes or declared members other than those shown below.

Template parameters

LayoutMapping

-

a layout mapping type that meets the requirements of LayoutMapping

Data members

Member name	Definition
mapping	calculated mapping of type LayoutMapping. It is declared with [[no_unique_address]] attribute. (public member object)
offset	calculated offset of type std::size_t. (public member object)

All these members have default member initializers where each data member is value initialized.
