Choose Enum+Match in Rust when the set of variants is closed and known upfront, and prefer Trait+Impl abstractions when you need extensibility and open-ended polymorphism. Decision criteria are based on openness and future extensibility requirements.

Implement safe state transitions in Rust using the Typestate pattern and RAII to enforce valid state changes via compile-time checks. This technique encodes state machines directly into the type system to eliminate runtime errors.

Apply the Strategy and Decorator patterns in Rust by utilizing traits to define shared behavior and composition to wrap objects. This provides idiomatic, flexible abstractions rather than relying on ad hoc solutions for feature development.

Yes, you can refactor ad hoc abstractions into maintainable Rust code by applying idiomatic design patterns like Adapter, Bridge, and Template Method. This ensures scalable architecture decisions and consistent design guidance during refactoring.

The Typestate pattern in Rust can increase code complexity and cause signature bloat when state machines are highly dynamic. It is best constrained to scenarios where compile-time checks are absolutely critical for preventing invalid operations.
