Could you offer some insight or examples of where or how C permits or enabled more-precise control than is permitted or enabled by Rust?

  You need unsafe in Rust just to do a doubly-linked list.

    Yes, I agree, you can implement a doubly-linked list in Rust exactly as you can in C, with the same precise control. You can even implement intrusive collections: https://docs.rs/intrusive-collections/ https://docs.rs/intrusive-collections/ Unsafe is a normal part of the language, and how you manually implement precise control behind a safe reusable abstraction whose correct use can be verified by the compiler. Do you have any examples of precise control you can express in C, but can't express in Rust?
