Lightning Talk: Spanny: Abusing C++ mdspan Is Within Arm’s Reach
summary
C++23 mdspan gets repurposed into hardware IO by implementing an mdspan accessor policy that talks to a robot arm over a serial port, uses a std::future to asynchronously drive bin checks, and employs a compile-time fold expression for bounds validation. The result is a view that maps beer-bin coordinates to live sensor queries, the arm iterates through all bins and reports occupancy, and the demo completes successfully printing each bin state.
