Lesson 4
Choosing and Applying Design Patterns to Solve Real-World Problems in Rust
Introduction

Welcome to the final lesson of the "Applying Design Patterns to Real-World Problems in Rust" course! 🎉 Kudos to you for making it all the way here. In this ultimate segment, you'll put all the design patterns you've learned into practice by tackling a variety of real-world challenges.

In the upcoming hands-on activities, you'll be challenged to identify and implement the most suitable design patterns for different problem scenarios, further sharpening your skills in crafting robust and efficient software solutions with Rust.

Design Patterns

In the practices following this lesson, you'll encounter situations where you need to choose among all the patterns you've covered so far, so it's better to quickly recap them:

Design Pattern TypePatternDescription
Creational PatternsSingletonEnsures a type has only one instance throughout the application, providing a global point of access.
BuilderFacilitates constructing complex objects step-by-step.
Abstract FactoryOffers an interface for creating related families of objects.
Factory MethodDefines an interface for creating objects, allowing specific implementations to alter the types of objects that are created.
Structural PatternsCompositeManages objects in a tree structure to represent part-whole hierarchies, allowing clients to treat individual objects and compositions uniformly.
AdapterEnables cooperation between incompatible interfaces by wrapping one interface around another.
DecoratorDynamically adds responsibilities to objects without altering their structure, providing a flexible alternative to subclassing for extending functionality.
Behavioral PatternsStrategyDefines a family of algorithms, encapsulates each one, and makes them interchangeable, allowing the algorithm to vary independently from the clients that use it.
ObserverImplements a subscription model to notify multiple objects about any events that happen to the object they're observing.
CommandEncapsulates a request as an object, allowing for parameterization and queuing of requests.

Now it's time to put your knowledge into action! 💪 By the end of this unit, you'll gain practical experience not only in recognizing design patterns but also in effectively applying them to solve complex, real-world problems.

Let's dive into the practice section and start applying these design patterns to build our smart home solutions in Rust! 🦀
