Function git_repository::discover::is_git

pub fn is_git(git_dir: impl AsRef<Path>) -> Result<Kind, Error>

What constitutes a valid git repository, returning the guessed repository kind purely based on the presence of files. Note that the git-config ultimately decides what’s bare.

Returns the Kind of git directory that was passed, possibly alongside the supporting private worktree git dir

Note that .git files are followed to a valid git directory, which then requires

• a valid head
• an objects directory
• a refs directory
