Using separate Rust Structs and Traits rather than class inheritance prevents tight coupling and deep,
unmaintainable hierarchies by favoring composition over inheritance.Key Advantages of Structs and TraitsSeparation of Concerns:
Data (fields inside a struct) and behavior (methods inside an impl or trait) are completely decoupled.
No Fragile Base Class Problem:
Changes to a parent class in traditional OOP can break subclasses unexpectedly;
traits define standalone shared behavior without hidden state dependencies.
Flexible Composition:
You combine small, focused traits instead of forcing objects into a rigid "is-a" taxonomy.
Zero-Cost Abstractions:
Using generics with trait bounds lets the compiler optimize dispatch statically with no runtime performance penalty.
