- You cannot actually 'turn off the borrow checker' in Rust, and doing so is discouraged.
- A macro exists to suppress many borrow checker errors for educational purposes, but it's unsafe and not for production use.
- The macro wraps references with an unsafe function to unbind their lifetimes, making the borrow checker ignore them.
- Using the macro can allow unsound and unsafe code that may fail unpredictably and dangerously.
- The approach has limitations and cannot suppress all borrow checker errors, such as those from implicitly created references or lifetime composition issues.
- Raw pointers should be used for raw pointer behavior, not this macro, as Rust's references are not pointers.
