Subtyping and variance is a concept that works in the background, making your life easier without you knowing about it. That is, until it starts making your life harder instead. It’s a good idea to know about it, in case you end up being a fool li...

Imagine you want to create a new library in Rust. All it does is wrap up a public API that you need for something else, like the Spotify API or maybe a database like ArangoDB. It’s not rocket science, you aren’t inventing something new or dealing ...

Hello! I’ve recently had the pleasure of giving a talk at this year’s TremorCon. I really enjoy public speaking, so this has been an excellent opportunity to get better at it (let me know your thoughts!). In case you missed it, you can check out t...

Welcome to the final article of this series! Here I’ll showcase some clean-ups and optimizations I may or may not have performed yet, so that our plugin system can get closer to production. I will also run benchmarks for some of these to ensure th...

Welcome to one of the last articles of this series! Previously, we covered how to use external dependencies to lessen the work necessary to implement our plugin system. Now that we know how to actually get started, we’ll implement it once and for ...

Previously in this series, I covered how the plugin system could be implemented from scratch. This is a lot of work if you’re dealing with a relatively large codebase and therefore a complex interface in your plugin system, so let’s see how we can...

This article in the Rspotify series describes my journey of basically rewriting the entirety of this Rust library; around 13 months of work (in my free time), starting at September 2020, up until October 2021. I think this has given me enough expe...

In the last article of this series I wrote some simple experiments of plugins both with WebAssembly and dynamic loading. After discarding Wasm for this specific plugin system, I wanted to try to get a more realistic example with dynamic loading an...

Welcome to the second article of my “Plugins in Rust” series! Here I will try to actually write some simple code of what a plugin system might look like, and try to answer any questions that may arise while doing so. Even though the project is spe...

Rust makes it very easy to express conditional compilation, especially thanks to Cargo “features”. They’re well integrated into the language and are very easy to use. But one thing I’ve learned by maintaining RSpotify (a library for the Spotify AP...

Welcome to the “Plugins in Rust” series! During the next months I’ll be involved in a project with Tremor, for which I need to implement a Plugin System. The goal is to maximize modularity and reduce Rust’s wild compilation times. The implementati...

Optional or default parameters are a very interesting feature of some languages that Rust specifically doesn’t cover (and looks like it won’t anytime soon). Say your library has lots of endpoints like so: fn endpoint<T1, T2, T3, ...>(mandato...
