 Rust guarantees memory safety and data race freedom through its type checker, which enforces *ownership* and *borrowing* rules. However, adhering strictly to these rules can limit expressiveness and restrict certain high-performance implementations. To address this limitation, Rust allows programmers to relax some type system checks within `unsafe` blocks. The challenge, however, is that maintaining type system invariants within these relaxed blocks becomes the programmer's responsibility.
