The Singleton pattern ensures a class has only one instance and provides a global point of access to it. In Rust, this is commonly achieved using static combined with lazy initialization via lazy_static. This avoids unsafe mutable global state. Our code defines a Logger struct and uses lazy_static to create a single, …

The Prototype pattern creates new objects from an existing object, a prototype, rather than using a traditional constructor. This is useful when the creation process is costly or complex, or when the class and its objects should remain unchanged. In Rust, this is elegantly achieved using the Clone trait and …

The Factory Method is a creational design pattern that provides an interface for creating objects, but lets subclasses decide which class to instantiate. It promotes loose coupling by allowing the client to work with an abstract type, deferring the concrete class selection to factory subclasses.

The Builder pattern allows for the construction of complex objects step-by-step. It separates the object construction logic from its representation, enabling the creation of different variations of the object without altering the core construction process. This is achieved through a builder struct that holds the …

The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes. It’s a creational pattern that promotes loose coupling and allows for easy switching between different “themes” or variations of objects.

The Peer-to-Peer (P2P) pattern enables direct communication and resource sharing between nodes (peers) in a network, removing the need for a central server. This example uses Rust’s asynchronous runtime (tokio) and UDP sockets to simulate a simple P2P network where peers can broadcast messages to each other. Each …
