Crate one_based

Provides OneBased* unsigned int types, which wraps several integers as 1-based index.

Example:

let v: OneBasedU32 = "5".parse().unwrap();
assert_eq!(v.as_zero_based(), 4);
assert_eq!(v.as_one_based(), NonZeroU32::new(5).unwrap());

let v: Result<OneBasedU32, OneBasedError> = OneBasedU32::from_one_based(0);
assert_eq!(v.unwrap_err(), OneBasedError::ZeroIndex);
