[][zero_based_index] [][zero_based_index] [][zero_based_index]

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 zerobasedindex::ZBI;

let zbi = ZBI(2usize); asserteq!(zbi.tolen(), Some(3)); ```

Base case with zero_based_index::AsZBI

``` use zerobasedindex::{ZBI, AsZBI};

let zbi = 2.aszbi(); asserteq!(zbi.to_len(), Some(3)); ```

Corner case

``` use zerobasedindex::ZBI;

let zbi = ZBI(usize::MAX); asserteq!(zbi.tolen(), None); ```
