In my previous article, I discussed how Rust enums should be strongly considered when the solution benefits from a state machine. The strongest argument for this is the fact that the Rust compiler will inform you when a state variant isn't covered in a match expression. This was stemmed from a state pattern example provided by the official Rust book. The sample scenario they used was an article that was required to go through the status of Draft, PendingReview, and Approved. Using a similar strategy as I explained in my original article, I came up with the following code: post.rs…

Introduction:In the previous article, we explored the importance of design patterns in software development and how they provide proven solutions to common problems. We discussed how choosing the right pattern is like selecting the appropriate tool from your toolbox. In this article, we'll dive deeper into the Strategy pattern and provide a practical, real-world example of its implementation using Java. What is the Strategy Pattern?The Strategy pattern is a behavioral design pattern that allows you to define a family of algorithms, encapsulate each one, and make them interchangeable. It lets the algorithm vary independently from clients that use it. The…
