debian version handling in rust

This simple crate provides a struct for parsing, validating, manipulating and comparing Debian version strings.

It aims to follow the version specification as described in Debian policy 5.6.12 and consistent with the behaviour of dpkg.

Example:

use debversion::Version;

let version: Version = "1.0-1".parse().unwrap();
assert_eq!(version.epoch, None);
assert_eq!(version.upstream_version, "1.0");
assert_eq!(version.debian_revision.as_deref(), Some("1"));

let version1: Version = "1.0-0".parse().unwrap();
let version2: Version = "1.0".parse().unwrap();
assert_eq!(version1, version2);

let version1: Version = "1.0-1".parse().unwrap();
let version2: Version = "1.0~alpha1-1".parse().unwrap();
assert!(version2 < version1);
