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 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 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 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…
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 Sometimes, for reasons of efficiency, it can be quite handy to keep a pool, that is non-empty set, of initialized objects ready. This can be the case in for instance when you have database connections, which are expensive to…
Introduction Dependency Injection is simply said, the idea that your classes should depend on abstraction, i.e. the abstraction of a datasource for example, rather than on concrete implementations. This means that classes will depend on interfaces rather than on real…
Introduction A couple of weeks ago I came across a well-written article by Mayank Choubey, where he did a performance comparison between a Web API written in Go using the Fiber framework and the Actix framework written in Rust. In…
Introduction In Design Patterns, the Iterator is a way of traversing over a container, that is access each of the container’s elements. It is used as a convenient way to traverse over lists or arrays, but it could also be…
Introduction When deciding on which IDE to use, one of the most important things is the debugging experience. In this short article I will try and share my experience debugging the same code with Visual Studio Code and RustRover Coming…
Introduction In one of my previous articles I wrote about RustRover, an IDE by Jetbrains, which came out last week (Sep. 13th 2023) in an Early Access Preview. In that article I reviewed this otherwise great product. However it occurred…
Introduction Considering Rust’s popularity it is quite surprising that no dedicated IDE has come out for this language. That all changed today, the 13th of September 2023, when RustRover, Jetbrains’s new Rust came out in Preview. Of course, I could…
Introduction In this post I described how to build a simple Web API in Rust with Actix, Diesel, and Postgres. Now it is time to deploy this app. Prerequisites In order to follow along, you will need the following: Building…
Introduction For the past year I have been experimenting with Rust. So, now it is time for a simple real project. What will be build? In this short series we will build a simple REST API to administer events. Events…
