Somtimes, leaps of faith are needed to achieve true greatness. It’s even more impressive if you do a leap of faith in a car, but why not take advantage of the safety features available, and buckle_up!?

pub fn parse(arbitrary_user_input_from_the_wilds: &[u8]) -> u32 {
    buckle_up!({
        std::str::from_utf8_unchecked(arbitrary_user_input_from_the_wilds).parse::<u32>().unwrap()
    })
}

let input = b"12345";
assert_eq!(parse(input), 12345);
