Definitely already assumes you know at least 1 other programming language
and how to write software — this is not a first language book or appropriate for
a beginner. That is OK, given Rust’s niche and (mostly necessary) complexity.
(Still, I can imagine the language having a Gc someday, and
perhaps an additional prelude, to make it more inviting for beginners. A
tangent...)
Overall very nicely done, and covers some different stuff than The Rust
Programming Language. I have read both and got value from having read both,
and recommend that if you have time.
If you only have time to read 1 Rust book cover-to-cover, make it this one — although RPL is a very close second and you’ll be well off if you read
it instead.
The book binding is not as fancy as O’Reilly books of old — it’s not holding
up as well as did my Camel Book in decades long past. Alas. Some typos, and
sometimes code is formatted in a strangely small font.
