It comes with the utility class template `std::extents` to describe the integral extents of a multidimensional index space. Practically, `std::extents` models an array of integrals, where some of the values can be specified at compile-time. However, `std::extents` behaves very little like an array. A not

Layout customization was originally motivated in [P0009R18] with considerations for interoperability and performance, particularly on different architectures. Moreover, [P2630R4] introduced `submdspan`, a slicing function that can yield arbitrarily strided layouts. However, witho

Mailing Date 2026-07 Post-Brno Author(s) Mark Hoemmen, Rob Parolin Target Audience LEWG Tracking issue View on GitHub Abstract Given an accessor `a` of type `A`, a “const element type version of `a`” (if it exists) is an accessor `b` of a possibly different type `B`, where
