Taking Template Classes Further with Opaque Types & Generic NTTPs

Explore advanced techniques for designing expressive template classes using C++20 features in this CppNow conference talk. Delve into opaque types and type erasure to reduce template parameter bloat, and learn how generic non-type template parameters (NTTPs) can create powerful embedded domain-specific languages. Discover how these approaches can be applied to solve long-standing challenges in generic multidimensional arrays. Gain insights into leveraging C++20 metaprogramming techniques to extend the capabilities of mdspan and discuss the potential impact of making C++ kind-generic for generative programming. Presented by Joel Falcou and Vincent Reverdy, experts in generative programming and high-performance computing.
