Edit: looks like it's a few bucks less on Amazon

Taking a wild guess here, but it sounds like you maybe referring to issues addressed by Non-Lexical Lifetimes (NLL)?
Reference: https://github.com/rust-lang/rfcs/blob/master/text/2094-nll....
NLL are a part of Rust 2018 Edition.
Three complementary books are the best resources:
- The Official book: https://doc.rust-lang.org/book/
- The Rust By Example book : https://doc.rust-lang.org/rust-by-example/
- Programming Rust (O'Reilly) : https://www.amazon.com/Programming-Rust-Fast-Systems-Develop...
