Versions

A library for parsing and comparing software version numbers.

We like to give version numbers to our software in a myriad of different ways. Some ways follow strict guidelines for incrementing and comparison. Some follow conventional wisdom and are generally self-consistent. Some are just plain asinine. This library provides a means of parsing and comparing any style of versioning, be it a nice Semantic Version like this:

1.2.3-r1

...or a monstrosity like this:

2:10.2+0.0093r3+1-1

For the Haskell version of this library, see here.

Examples

```rust use versions::Versioning;

let good = Versioning::new("1.6.0").unwrap(); let evil = Versioning::new("1.6.0a+2014+m872b87e73dfb-1").unwrap();

assert!(good.isideal()); // It parsed as a SemVer. assert!(evil.iscomplex()); // It parsed as a Mess. assert!(good > evil); // We can compare them anyway! ```

Features

You can enable Serde support for serialization and deserialization with the serde feature.
