CppCon 2018

Data de-serialization is a surprisingly common task in game console emulation (kernel interfaces, driver communication, and file IO), and to address it we usually use repetitive boilerplate code that is often nothing but error-prone and unmaintainable. How can modern C++ help?

We take a look at the interprocess communication subsystem of the Nintendo 3DS and see how generative programming tools (variadic templates, function reflection, metaprogramming) and a declarative approach give us wins in performance, maintainability, and correctness.

The takeaway of this session is a glimpse at generators, declarative interfaces, and how to use them to solve serialization-like problems with minimal effort and maximum reusability.
