How to fix Rust E0133 use of unsafe requires unsafe block

Fix Rust E0133 by wrapping unsafe operations in an unsafe block to acknowledge manual safety verification.

Wrap the unsafe operation in an unsafe block to acknowledge you have manually verified its safety.

unsafe {
    // Your unsafe code here
}

The unsafe block tells the compiler you accept responsibility for ensuring the code inside doesn't violate Rust's safety guarantees, such as dereferencing raw pointers or calling unsafe functions.
