CppCon 2018: Simon Brand “How to Write Well-Behaved Value Wrappers”

http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — There are many useful generic types which wrap a number of values up into one object, e.g. std::optional or std::tuple. These types are conceptually very simple, but designing and implementing them to be as optimal and consistent as possible is deceptively difficult. This talk will outline key considerations, show why they matter by examining the assembly generated from compilers, and describe a number of solutions for problems which arise. Finally, a number of C++ standards papers which could ease the implementation burden for these types will be discussed. Topics covered will include implicit/explicit constructors, conditional deletion of special member functions, propagation of special member triviality, noexcept correctness, private inheritance, and comparison operators. — Simon Brand, Microsoft C++ Developer Advocate Simon is a C++ Developer Advocate at Microsoft.
