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…
Introduction The Bridge pattern is a design pattern that is meant to “decouple an abstraction from its implementation so the two can vary independently”. To that end this pattern can use encapsulation, aggregation and also inheritance in order to separate…
