How deep is your understanding of the Rust programming language and its features?

I am familiar with the main features of the Rust language, such as the ownership system, borrowing, and lifetimes, which ensure memory safety without a garbage collector. I also understand the concept of pattern matching, working with Option and Result types for error handling, and the absence of null. I know that Rust is actively used for systems programming and creating high-performance applications with compile-time safety.
