Rust Is Beyond Object-Oriented, Part 3: Inheritance (2023)

4 months ago

Rust does not support traditional OOP inheritance, focusing instead on traits and structs for polymorphism and encapsulation.
Inheritance in OOP is criticized for conflating interface implementation with state management, leading to design issues.
Rust's alternative to inheritance includes using enums for sum types, struct composition, and trait-based polymorphism.
The article suggests that inheritance is rarely the best solution, advocating for Rust's more explicit and flexible patterns.
Examples of Rust patterns replacing inheritance include enum hierarchies, struct composition, and policy-based design.
