Introduction As C# developers, we have all been there. You are calling a method like GetUser(id), and you wonder: does it return null if the user is not found? Or does it throw a NotFoundException? Or perhaps even and InvalidOperationException?…
Introduction In this article I discussed the implementation of the Abstract Factory pattern. The Factory Method is simply an extension of that pattern. Creating an object can sometimes be complex. A factory-method can abstract this complexity away, and let subclasses…

Introduction The prototype-pattern is a creational design pattern that allows us to create new objects by cloning existing ones, i.e. the existing objects function as a kind of template. This can save time in some cases when for example an…
Introduction The Abstract Factory Pattern is a way to group the creation of related objects, like products of a certain brand or make by building a common factory interface. If this all sounds abstract, a picture can help: A short…

Introduction The flyweight pattern is a pattern that helps minimize memory usage by sharing and reusing data. A common example is wordprocessor where each character not only holds the character like ‘A’ but also things like markup and formatting data.…
Introduction The Adapter pattern is used to make one interface compatible with another. It allows objects with different, and therefore incompatible interface to work together. If you for example want to bring an existing class into your system with an…

Introduction The proxy-pattern is a very useful design pattern. The basic function is to make sure that a caller has no direct access to the instance of an object but rather goes through another class which does have access. I…
Introduction The mediator pattern is a pattern used when you want to simplify communication i.e. message dispatching in complex applications. It involves building a mediator where each objects can delegate its communication, and which routes the messages to the right…
Introduction Writing concurrent code in Rust can be a real challenge. You’re constantly thinking about shared state, race conditions, and how to safely pass data between threads without the whole program crashing. But what if you need to know when…
Introduction Building robust, real-time applications in Rust can often feel like a juggling act. You want a responsive user interface, but you also need to handle complex, asynchronous data updates—all without sacrificing Rust’s core promise of memory safety and thread…
Introduction The strategy pattern is a behavorial design pattern that allows you to define a family of algorithms, encapsulate them as an object, and with the help of interfaces make them interchangeable. The use of type annotations also helps to…
Introduction The builder pattern is a creational design pattern, i.e. it is a pattern for creating or instantiang objects of classes. It is used for breaking down the construction process, into smaller, more manageable and testable steps. It looks like…
