I think Amos's title here is a little tongue-in-cheek by the way - it's more like a half-hour to skim through it, but with this at hand you'll be in a much better place to start writing some toy rust programs before you dive into more in-depth books like "The Rust Programming Language".
I currently have (and like) that and the O'Reilly book "Programming Rust", and found them sufficient for initial exploration. I'm now trying to internalise the contents of "Effective Rust" (also O'Reilly) and "Rust for Rustaceans" from Free Starch Press - the latter of which I would say is the most advanced of these.
There's still plenty I don't understand, but that's more about the minimal amount of time I've spent dabbling rather than any deficiency in these resources (so far as a dabbler can tell).
