Gutenberg-rs
A couple of years passed since i wrote GutenbergPy. It has since gained some traction. A few people contacted me for information, wanting to help, and using it in their projects. I won’t say it’s famous; in fact, it has gained little traction in terms of people using it versus time since launch; however, it is a niche project, and for what it did, I consider it a minor success (there already existed one library with a better name that did almost the same things but slower with more resource consumption and less maintained).
