THEN In the Rust FFI functions that return *mut i8, cast the result of CString::into_raw() (which returns *mut u8) to *mut i8 using `as *mut i8`. Alternatively, replace `into_raw()` with `as_ptr() as *mut i8` to align pointer types with the function signature. This resolves the compile-time type mismatch.

// Change return statements from:
// CString::new(...).unwrap().into_raw()
// to:
CString::new(...).unwrap().into_raw() as *mut i8
