Type-Safe Interfaces with Modern C++ - std::variant – Use Cases

The video explores the use of variants in C++ for representing choices between types, error handling, state machines, and recursive data structures. It compares traditional polymorphism with variants, highlighting the benefits of using variants in scenarios with a closed set of types. Examples include messaging applications, error handling, and state machines in games. The video also covers recursive data structures and how variants can be used to model them efficiently.
