Rust was a pain in the ass until I stopped trying to write C code in it and started writing idiomatic Rust. I don’t know the author of this blog, but he mentions extensive C++ experience which makes me wonder if he’s trying to write C++ in Rust.

Maybe not! Maybe it’s truly just Rust being stubborn and difficult. However, it’s such an easy trap to fall into that I’ve gotta think it’s at least possible.

Are there examples one can learn from about idiomatic rust? I would appreciate either books or projects to learn from.

https://doc.rust-lang.org/book/ is great. I’d been writing Rust for months before I started reading it and still began learning new things from the start. Oh, that’s why it does this!

Edit: Oh! And use “cargo clippy” regularly. It makes excellent recommendations for how to make your code more idiomatic, with links to docs explaining why it’s nicer that way.
