Personally, the Rust Book (2nd edition) seems like good teaching material (from the perspective of a junior self-taught JS dev). What would make it even better is adding a few questions at the end of each chapter, much like the homework in https://www.seas.upenn.edu/~cis194/spring13/lectures.html https://www.seas.upenn.edu/~cis194/spring13/lectures.html. These don't have to be large projects, but they shouldn't be a simple rehash of the prior code blocks either. Ideally they pose a challenge that, when solved in a "typical beginner way" (whatever that is), cause the reader to stumble over some common gotchas. The first few chapters actually mention and explain some of those gotchas (like ownership in regards to returning from functions or accepting a reference). The difficulty probably lies in not outright explaining everything, but not making the reader feel completely lost at the same time. Then again, questions can always be added later on and if the basic reading material is good (which it is!), it's only going to make an already good source even better. I guess that's meant to say thanks for the Rust book.
