Another book I found very helpful is Programming Rust [1], it expands on many concepts in the Rust book, the chapters on closures, iterators, collections, concurrency and async have very good explanations on how things work.

I found the Rust Programming Language book [1] very helpful for learning, and with rust installed you can open it by typing rustup doc --book.

I played with it recently, being a PostgreSQL extension I found it easy to implement a rust client [1] to test ingestion rate performance, on my laptop was able to insert ~600K rows/sec.

The documentation on their website [2] is also very good.
