Breaking Dependencies - C++ Type Erasure Implementation Details - Lecture

Dive into an in-depth exploration of C++ Type Erasure implementation details in this CppCon 2022 conference talk by Klaus Iglberger. Learn about the superiority of Type Erasure over inheritance for dependency management, and discover various implementation techniques ranging from simple 20-line wrappers to advanced performance optimization strategies. Gain insights into owning and non-owning Type Erasure Wrappers, manual implementation of virtual functions, and Small Buffer Optimization (SBO). Acquire the knowledge and skills necessary to effectively implement and utilize Type Erasure in your own C++ projects, reducing coupling between software entities and improving overall design.
