This repository requires Rust language/compiler to build from source

As of last update to this ReadMe file, the recommended method of installing Rust is via the installer script...

curl --proto '=https' --tlsv1.2 -sSf | sh

Quick Start

This repository is a Rust library, define it as a dependency within a project Cargo.toml file...

Cargo.toml (snip)

version_operators = "0.0.1"

Check Rust -- Doc -- Specifying Dependencies for details about defining dependencies.

Then include within a source file via use statement...

src/ (snip)

use version_operators::Version;


src/ (example)

use version_operators::Version;

fn main() {
    let version = Version::from_str("1.14.3");

    let expected = vec![1, 14, 3];

    assert_eq!(version.to_vector(), expected);

Check the examples/ directory of this repository for more detailed examples of how this project may be utilized within other applications, use cargo run --example <name> to execute, eg...


cargo run --example version-compare '1.14.3' '-lt' '1.14.4'
#> true

cargo run --example version-compare '1.14.3' '==' '1.14.4'
#> false


cargo run --example version-math '1.14.4' '-add' '1.14.3'
#> [2, 28, 7]

cargo run --example version-math '1.14.4' '-sub' '1.14.3'
#> [0, 0, 1]


Until version 0.1.0; methods, data structure properties, and implementation name(s) may have names and/or behavior change!

This repository may not be feature complete and/or fully functional, Pull Requests that add features or fix bugs are certainly welcomed.

Currently math and comparison operators start with the most significant bits of each version. This means that when operating on versions of unequal length it may be useful to zero-pad the shorter version...

use version_operators::Version;

fn main() {
    let version_one = Version.from_str("1.14.3");
    let version_inc = Version.from_str("0.0.1");
    let new_version = version_one + version_inc;

    assert_eq!(new_version.to_vector(), vec![1, 14, 4]);

Check source code of examples/ for an example of targeting a portion of a version to increment...

cargo run --example version-increment '1.14.3' '1'
#> [1, 15, 3]


Options for contributing to version and rust-utilities


Start making a Fork of this repository to an account that you have write permissions for.

  • Add remote for fork URL. The URL syntax is<NAME>/<REPO>.git...
cd ~/git/hub/rust-utilities/version_operators

git remote add fork<NAME>/version_operators.git
  • Test changes via cargo...
cargo test
  • Commit your changes and push to your fork, eg. to fix an issue...
cd ~/git/hub/rust-utilities/version_operators

git commit -F- <<'EOF'
:bug: Fixes #42 Issue


- `<SCRIPT-NAME>` script, fixes some bug reported in issue

git push fork main

Note, the -u option may be used to set fork as the default remote, eg. git push -u fork main however, this will also default the fork remote for pulling from too! Meaning that pulling updates from origin must be done explicitly, eg. git pull origin main

  • Then on GitHub submit a Pull Request through the Web-UI, the URL syntax is<NAME>/<REPO>/pull/new/<BRANCH>

Note; to decrease the chances of your Pull Request needing modifications before being accepted, please check the dot-github repository for detailed contributing guidelines.
