Implementation

Use unsafe Rust to work with raw pointers and FFI.

Requirements:

Use raw pointers (*const T, *mut T)
Dereference pointers in unsafe block
Implement FFI to C function
Explain safety implications

Why This Matters

unsafe is Rust's escape hatch and its social contract: the standard library, tokio, and every FFI binding contain unsafe blocks wrapped in safe APIs. The Rust-in-Linux-kernel work is precisely this discipline — knowing what invariants you must uphold when the borrow checker cannot check them for you.
