This is an appendix to the course. It contains additional material that may or may not be interesting to you.
You finished the course (or you're skipping ahead, which is fine too). A bit of background, in case you're curious.
There's no shortage of Rust resources. The official book is excellent, and you should read it. So is Rust by Example, and plenty of others.
What was missing, for me, was a path you could open in a browser and just do. Not a book to read on the couch, not a lecture to watch on 2x speed: a sequence of small, real problems with tests that turn green. Something where the code leaves your fingers and lands in the machine right away.
These exercises started as a folder on my laptop, the kind of thing I'd pull out whenever someone asked "where do I start with Rust?" Over the years it grew into a structured path through the language. This site is that path, with an editor attached.
The course covers the core mechanics. Real fluency comes from using those mechanics on problems that matter to you. A few suggestions:

Thanks for spending time here. Now go write some Rust.
