In this chapter, we moved beyond defining concrete types and explored how to write code that is flexible, reusable, and safe. We started by examining traits, which allow us to define shared behavior across different types. We learned that by focusing on what a type can do rather than what it is, we can write functions that accept any data capable of performing a specific action, similar to interfaces in other languages. We also covered the orphan rule for implementations and the trade-offs between static dispatch and dynamic dispatch using trait objects.
Next, we introduced generics as the primary tool for reducing code duplication. By using type parameters such as <T>, we saw how to write a single function or struct that works with any data type. We discussed how trait bounds allow us to restrict these generics to ensure they support the operations we need. Crucially, we learned about monomorphization, the compiler process that generates specific code for each concrete...
