How Rust approaches the three core object-oriented concepts — objects, encapsulation, and inheritance — and why the language takes a different path from classical OOP

• Objects Contain Data And Behavior
• Encapsulation With Modules And Visibility
• Inheritance And Polymorphism Via Traits

How to achieve runtime polymorphism in Rust using trait objects, the rules of object safety, the mechanics of dynamic dispatch, and the trade-offs between generics and trait objects.
