Struct Repository 

pub struct Repository { /* private fields */ }

Represents the state associated with a Git repository.

Many other types in this crate are derived from methods in this struct.

Implementations

fn main() {
    let options = get_options_or_exit();
    let repo = init_repository_or_exit(&options.path_to_repo);
    let head_oid = match options.head_revision {
        HeadRevision::Head => repo.head().unwrap(),

}

pub fn diff_commit(&self, commit: impl ToCommit) -> Result<Diff, Error>

Get the Diff of a commit.

If the commit has a parent, then it the diff will be a comparison between itself and that parent. Otherwise, the left hand side of the diff will pass nothing.

pub fn diff_file<P: AsRef<Path>, R: Revision>( &self, path: &P, from: R, to: R, ) -> Result<FileDiff, Error>

Get the FileDiff between two revisions for a file at path.

If path is only a directory name, not a file, returns a FileDiff for any file under path.

pub fn oid(&self, oid: &str) -> Result<Oid, Error>

Parse an Oid from the given string.

pub fn root_dir<C: ToCommit>(&self, commit: C) -> Result<Directory, Error>

Returns a top level Directory without nested sub-directories.

To visit inside any nested sub-directories, call directory.get(&repo) on the sub-directory.
