Introduction The Balking Pattern might not be widely known, but it plays a crucial role in preventing certain actions on objects based on their state. For instance, attempting to read the contents of an unopened file should not be allowed.…
Introduction Using a fluent interface can make your code easier to read. This pattern allows you to connect method calls, as each method returns the object or context. When implemented well, it can create a kind of specialized language for…
Introduction Using a fluent interface can make your code easier to understand. This pattern allows you to link method calls, where each method returns the object or context. When implemented well, it creates a specialized language for a specific domain.…

Introduction Sometimes, it’s handy to separate when a method is called from when it actually runs. That’s where the Active Object design pattern comes in. It lets us build more flexible and concurrent systems. One key feature is that each…
Introduction Sometimes you need to decouple method execution from method invocation. In such cases the Active Object design pattern is a good choice. It allows for more flexible and above all concurrent systems. One the of the hallmarks of this…
Introduction Most applications require business rules, such as data validation. It’s crucial to implement these rules in a way that’s flexible, clear, and easy to maintain. The Specification pattern offers a solution, allowing the creation of reusable business rules that…
Introduction The Servant pattern is a way of organizing code where one special object helps out a bunch of other objects. This helper object provides some functions to these objects, so they don’t have to do the same things over…

Introduction Resource Acquisition and Initialization means the following: In some programming languages like Rust, this is built into the language. But in Go, which is not entirely object-oriented, we can do something similar using the “defer” keyword. Implementation in Go…
Introduction The extension object pattern is like adding extra features to something without changing what it is. It’s a bit like putting a gift inside another gift. In this case, Rust doesn’t directly support this pattern like some other languages,…
Introduction The extension object pattern is a clever way to add new features to an existing object without changing its original code. It’s like wrapping a present within a present – the outer one directs requests to the inner one.…
Introduction In delegation, you delegate a certain request to an object to a second object, which we call the delegate. This is almost like a subclass sending a request to its parent class. In Go we can achieve this functionality…
Introduction The composite pattern allows you treat a group of objects like a single object. The objects are composed into some form of a tree-structure to make this possible. This patterns solves two problems: We do this by doing the…
