Yeah 2022 was the year in which rust transitioned (to me) from "frustrating waste of time language" to "wait a minute, the standard library is really good, the tools are really good, I could probably make useful software with this".
Though curious why a book describing unsafe rust made rust click for you?
It made me better understand how Rust works and how it is designed, and in doing so, it really untangled how borrowing/ownership works.
I liken it to paint a tree, full of leaves which obscure its branches. I might never paint the branches, but understanding how the branches are shaped will help me draw a better tree.
This was in tandem with reading the Rust book, being active in the IRC, and writing programs to learn! The Rustonomicon just happened to have what I needed.
Definitely in the running!
I'd also recommend "The Moral Character of Cryptographic Work": https://web.cs.ucdavis.edu/~rogaway/papers/moral-en.pdf
