A very nice, engaging, and well-written introduction to the language. My only request for a future version is a chapter on futures, async, and asyn_await, which I have a hard time understanding, but seem to be the future of concurrent programming with Rust. I expect it’ll come in the future, though it might need its own book, too.

I only have that complaint because I’ve done enough poking at Rust to know about it; anyone unfamiliar with the development of futures won’t miss it here, and find it a super useful introduction to Rust. Highly recommended.
