Explore a comprehensive conference talk from CppCon 2022 that delves into the intricacies of C++ recognized user type categories. Gain insights into trivial types, standard layout types, implicit-lifetime types, aggregate types, and literal types. Learn about their differences, use cases, and importance in optimizing code. Discover the advantages and potential pitfalls of these language-recognized user types, and understand how to leverage their special provisions to write more efficient C++ code. Follow along as Nina Ranns, a seasoned C++ standard committee member, guides you through the nuances of these type classifications, helping you avoid undefined behavior and make informed decisions in your programming.
