Not quite the same as tagged algebraic union ("sum type" == Rust enum) are not (yet?) a language feature.

That being said, I recently integrated mir's Algebraic and Nullable into a project. Integration was pretty easy, and the code was clear and easy to understand. That being said, the terminology of "Some", "None", "Result" and "Err" in Rust are yet easier to understand.

Finally, in addition to `mir.algebraic`, `sumtype`, `Optional`, and `Result` packages, I would add that Tchaloupka's `expected` package looks great:

thanks, all is great, but it's better if we have an article explaining how to combine these
for real-world project.
