try_into is better than 'as' because of error handling
The try_into() method returns an i32 value wrapped within a Result.
unwrap: if this result does not emit an error. it will resolve with the value. unwrap in not suit for prod because input validation
The unwrap() method can handle the success value and returns the value of b as an i32 here
