We have spent the previous chapters defining concrete types such as structs and enums. These are excellent for modeling specific data, but real-world software often requires more flexibility! In real-world scenarios, we often need functions that can accept different types of data as long as they behave in a certain way.
In computer science, this concept is known as polymorphism. In Rust, we achieve this primarily through traits and generics. We will also cover lifetimes, which are a special form of generics that ensures references remain valid while our code becomes more abstract.
The first step toward writing flexible code is changing how we view our data. Instead ...
