The ISO-C++ proposal P0009 will add support for non-owning multi-dimensional array references to the C++ standard library. This repository aims to provide a production-quality implementation of the proposal as written (with a few caveats, see below) in preparation for the addition of mdspan to the standard. Please feel free to use this, file bugs when it breaks, and let us know how it works for you :-)

- C++17 backport (e.g., concepts not required)
- C++14 backport (e.g., fold expressions not required)
- Compile times of this backport will be substantially slower than the C++17 version
- C++11 backport
- Compile times of this backport will be substantially slower than the C++14 backport
- Macros to enable, e.g.,
__device__marking of all functions for CUDA compatibility
This implementation is header-only, with compiler features detected using feature test macros, so you can just use it directly with no building or installation. If you would like to run the included tests or benchmarks, you'll need CMake.
