Hands-On Data Structures and Algorithms with Rust

Objects and behavior

Organizing code in Rust is a bit different from regular object-oriented languages such as C#. There, an object is supposed to change its own state, interfaces are simple contract definitions, and specialization is often modeled using class inheritance:

class Door {    private bool is_open = false;    public void Open() {        this.is_open = true;    }}

With Rust, this pattern would require constant mutability of any Door instance (thereby requiring explicit locking for thread safety), and without inheritance GlassDoor would have to duplicate code, making it harder to maintain.

Instead, it's recommended to create traits to implement (shared) behavior. Traits have a lot in common with abstract classes in traditional languages (such as ...
