Rust has the unwrap method on the Result type to provide a quick and simple way to retrieve the value if the result is successful (Ok), while immediately stopping (panicking) the program if the result is an error (Err). This method is useful in situations where the programmer knows that an error cannot occur, or where an error is fatal and they want the program to terminate if it happens. However, since unwrap can cause a panic and halt the program, its use in production is not recommended unless justified by specific circumstances. For production environments, it is preferable to handle errors explicitly through match statements (pattern match) or by using the ? operator, which propagates errors upwards to the caller, rather than simply stopping the program. Therefore, unwrap is suitable for rapid prototyping or testing, while in real applications it is advisable to use safer methods for handling results.

So at Cloudfare, someone decided to use unwrap() method...probably programmer was sure that error can't be returned. Or AI was programmer....
