Newtype offering some utility methods for zero-based indices

In order to keep the lengths of method names reasonable, several abbreviations have been used, namely

• len for length;
• int for integer.
• zbi for zero-based index.

Examples

Base case

use zero_based_index::ZBI;

let zbi = ZBI(2usize);
assert_eq!(zbi.to_len(), Some(3));

Base case with zero_based_index::AsZBI

use zero_based_index::{ZBI, AsZBI};

let zbi = 2.as_zbi();
assert_eq!(zbi.to_len(), Some(3));

Corner case

use zero_based_index::ZBI;

let zbi = ZBI(usize::MAX);
assert_eq!(zbi.to_len(), None);
