When people asking my opinion for Rust, I loved to share them the Linkedin List implementation link: https://doc.rust-lang.org/src/alloc/collections/linked_list....

And the first feedback is why so many unsafe blocks? What is it Option<NonNull<Node<T>>> ? '_ ?

Another reason to share, if you can understand Linkedin List, you are free to code in Rust ;)
