Detailed Description

Example code from the "std::span in C++" presentation.

This presentation gives an overview of the std::span class template in the C++ library. It is meant to be for both C++ programmers as well as non C++ programmers to give a short intro to the static compile time capabilities of the C++ language.

std::span with it's non-type template parameter Extent shows a capability not present in many languages - the ability to specify info that is present only at compile time, and does not cost runtime space or time.
