nagios-range

This is a very small Rust library that simply parses a Nagios range as defined in the Nagios development guidelines.

Example

```rust use nagios_range::NagiosRange;

fn main() { let range = NagiosRange::from("@~:10"); assert!(range.isok()); assert!(range.isinside());

let start = range.start();
assert!(start.is_neg_inf());

let end = range.end().inner();
assert_eq!(end, Some(10));

} ```
