Welcome back! 🚀 We are embarking on an exciting journey into "Applying Design Patterns for Real-World Problems using Rust". This final course of the Mastering Design Patterns with Rust path will guide you in integrating all the design patterns you've encountered so far into real-world applications. In this first lesson, we will consider the Factory Method and Adapter patterns, demonstrating their utility by building an efficient and flexible smart home system. Get ready to enhance your coding toolkit and prepare to make your smart home management system more agile and future-proof. Let's dive in!

Before writing any code, it's vital to map out your design. This ensures the development of robust, scalable, and maintainable systems. Here’s how we plan to implement the Factory Method and Adapter design patterns in our smart home project:

1. Factory Method Pattern:

   • Purpose: To encapsulate object creation, allowing easier extension with minimal code changes.
   • Steps:
     • Define a trait (SmartDevice).
     • Create specific device structs (Thermostat, Light) implementing the trait.
     • Implement factory structs (ThermostatFactory, LightFactory) providing methods to create these devices.
