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, Error};

fn main() -> Result<(), Error>{ let range = NagiosRange::from("@~:10"); assert!(range.isok()); assert!(range?.checksinside()); assert!(range?.startisinfinite()); assert!(range?.check(5.0)); } ```
