25.4 Memory Handling in Unsafe Code
Even within unsafe blocks, Rust’s ownership model and RAII (Resource Acquisition Is Initialization) still apply. For instance, if you allocate a Vec<T> inside an unsafe block, it will be deallocated automatically when it goes out of scope.
However, unsafe code can bypass some of Rust’s usual safety checks. When employing unsafe features, you must ensure:
- No data races occur when multiple threads share memory.
- Memory safety remains intact (e.g., do not dereference pointers to freed memory, avoid double frees, and do not perform invalid deallocations).
