Gem version

What

Implement Ruby's Gem::Version comparison logic in Rust:

• Gem::Version
• Gem::Version tests

The main use case is for the Heroku Ruby buildpack https://github.com/heroku/buildpacks-ruby and associated ecosystem of managing Ruby logic inside of Rust.

Install

Add it to your cargo.toml:

$ cargo add gem_version

Use

use std::str::FromStr;
use gem_version::GemVersion;

let version = GemVersion::from_str("1.0.0").unwrap();
assert!(version < GemVersion::from_str("2.0.0").unwrap());
