This book naturally assumes that you've already read Rust's core book:

• The Rust Programming Language

Now, I know it sounds silly to say "if you wanna program Rust on this old video game system you should already know how to program Rust", but the more people I meet and chat with the more they tell me that they jumped into Rust without reading any or all of the book. You know who you are.

Please, read the whole book!

In addition to the core book, there's also an expansion book that I will declare to be required reading for this:

• The Rustonomicon

The Rustonomicon is all about trying to demystify unsafe. We'll end up using a fair bit of unsafe code as a natural consequence of doing direct hardware manipulations. Using unsafe is like swinging a sword, you should start slowly, practice carefully, and always pay attention no matter how experienced you think you've become.

That said, it's sometimes a necessary tool to get the job done, so you have to break out of the borderline pathological fear of using it that most rust programmers tend to have.
