§libgit2 bindings for Rust

This library contains bindings to the libgit2 C library which is used to manage git repositories. The library itself is a work in progress and is likely lacking some bindings here and there, so be warned.

The git2-rs library strives to be as close to libgit2 as possible, but also strives to make using libgit2 as safe as possible. All resource management is automatic as well as adding strong types to all interfaces (including Result)

§Creating a Repository

The Repository is the source from which almost all other objects in git-rs are spawned. A repository can be created through opening, initializing, or cloning.

§Initializing a new repository

The init method will create a new repository, assuming one does not already exist.

use git2::Repository;

let repo = match Repository::init("/path/to/a/repo") {
    Ok(repo) => repo,
    Err(e) => panic!("failed to init: {}", e),
};

§Opening an existing repository

use git2::Repository;

let repo = match Repository::open("/path/to/a/repo") {
    Ok(repo) => repo,
    Err(e) => panic!("failed to open: {}", e),
};

§Cloning an existing repository

use git2::Repository;

let url = "https://github.com/alexcrichton/git2-rs";
let repo = match Repository::clone(url, "/path/to/a/repo") {
    Ok(repo) => repo,
    Err(e) => panic!("failed to clone: {}", e),
};

To clone using SSH, refer to RepoBuilder.

§Working with a Repository

All derivative objects, references, etc are attached to the lifetime of the source Repository, to ensure that they do not outlive the repository itself.
