Explore a comprehensive conference talk on leveraging the C++ type system and templates to create efficient, safe, and reusable code. Learn how to utilize type-rich APIs for error prevention and improved readability, while implementing template techniques for zero-overhead reusable libraries. Dive into topics such as the Whole Value Pattern, constructors, explicit operations, runtime polymorphism, physical quantities, template metaprogramming, operator traits, and fixed-length strings. Discover the benefits of policy decisions, context-dependent runtime checks, and the differences between implicit and explicit operations. Gain insights into compilation versus templates, and understand how concepts can improve error messages. Master the art of creating lightweight abstractions that enhance code safety, genericity, and reusability in C++ programming.
