Can't push my modifications with the lib about git2-rs

It looks like the problem here is that the pass variable passed in is None and you're calling .unwrap(). I believe this is just the password encoded in the URL, and it will be None if there wasn't one. If you use .unwrap_or(...) with a default password (or one learned from elsewhere), I think that'd do the trick!

Sorry for the delay.
I've update my code, and the program seems to loop...

This is my code:

match branch_back_up.as_mut() {
    Ok(branch) => match branch.set_upstream(Some("back_up")) {
        Ok(_) => println!("Branch 'back_up' has been updated!"),
        Err(error) => println!("Error due to {}", error),
    },
    Err(error) => panic!("Canno't upstream the branch 'back_up', due to error {}", error),
}
let refname = match branch_back_up.as_mut() {
    Ok(branch) => branch.get(),
    Err(error) => panic!("ERROR: {}", error),
};
// Find remote
let mut r_remote = r.find_remote("origin").unwrap();
// Push branch
let mut callbacks = RemoteCallbacks::new();
callbacks.credentials(|user, pass, ctype| {
    return Cred::userpass_plaintext(user, pass.unwrap_or("MY_PASSWORD"));
});
let mut push_options = PushOptions::new();
push_options.remote_callbacks(callbacks);
match r_remote.push(&[], Some(&mut push_options)) {
    Ok(_) => println!("Branch has been pushed!"),
    Err(error) => println!("Error {}", error),
};

but, since less 10 minutes, the program is blocked on

README.md has been added!
Branch 'back_up' has been updated!

Did I missed something? :-/

I think that you may have to specify some refs of what to push? I always forget what you precisely need to pass in, but it may help to see a working code example as well, although that doesn't deal with branches much as it only works with the master branch
