I just think Rust is neat
Option<T> and Result<T,E> in Java
This project is an implementation of the Result- and Option API from Rust, with some omissions because they either have narrow use cases or simply don't make much sense in Java (such as take).
Part learning experience, part experiment. I was curious as to what these types would look like in Java, and whether they are good alternatives to null and throw, two of my least favorite design-decisions in Java. Furthermore, I wanted to figure out a general design pattern for tagged unions in Java. Much of the inspiration for this come from the answers to this question on StackOverflow.
