In this talk, we will take a tour around the `error` function. Starting from the simple use-cases and ending up with sophisticated yet developer-friendly error messages.
Among the many new features that landed in Scala 3, one of the lesser-known ones is the `compiletime.error` function. This seemingly simple function lets us define custom compile-time errors, bringing us a great leap forward in Scala's ability to provide developer-friendly compile-time safety.
But nothing is without complication. Despite the benefits, to fully utilize the power of the `error` function, for better or for worse, one has to take a deep dive into Scala's novel compile-time programming techniques. And what an exciting dive it is.
In this talk, we will take a tour around the `error` function. Starting from the simple use-cases and ending up with sophisticated yet developer-friendly error messages. Guided by a practical example, we will see how and why we can use the `error` function, as well as the accompanying compile-time programming techniques that will allow our error messages to really shine.
Join me for a fun and possibly opinionated talk about the state of Scala and other JVM languages.
This talk is my slightly expanded version of that statement, and should hopefully understand what "Free" is, what purpose it serves and where it came from.
In this beginner-friendly talk we'll try to find out using the power of Scala and functional programming techniques.
In this talk, I will cover three key concepts that emerged from reflecting on this past year of learning: making mistakes, helping others to help you and finding community.
In this session, I will guide you through two recent additions to Ox that I helped implement: channel operators and retries.
