Function built::util::get_repo_head

pub fn get_repo_head(
    root: &Path
) -> Result<Option<(Option<String>, String)>, Error>

Retrieves the branch name and hash of HEAD.

The returned value is a tuple of head's reference name and long hash. The branch name will be None if the head is detached, or it's not valid UTF-8.

If a valid git-repo can't be discovered at or above the given path, Ok(None) is returned instead of an Err-value.

Errors

Errors from git2 are returned if the repository does exists at all.
