Sharing code among types
An unusual feature of the Rust programming language is the decision to use traits over interfaces. The latter is very common across modern object-oriented languages and unifies the API of a class (or similar) to the caller, making it possible to switch the entire implementation without the caller's knowledge. In Rust, the separation is a bit different: traits are more akin to abstract classes since they provide the API aspect as well as default implementations. struct can implement various traits, thereby offering the same behavior with other structs that implement the same traits.
