Trait Implementations

impl Backend for LocalBackend

fn as_any(&self) -> &dyn Any

fn name(&self) -> &str

A unique name that identifies this backend. Written to .jj/repo/store/backend when the repo is created.

fn commit_id_length(&self) -> usize

The length of commit IDs in bytes.

fn change_id_length(&self) -> usize

The length of change IDs in bytes.

fn read_file( &self, _path: &RepoPath, id: &FileId ) -> BackendResult<Box<dyn Read>>

fn write_file( &self, _path: &RepoPath, contents: &mut dyn Read ) -> BackendResult<FileId>

fn read_symlink( &self, _path: &RepoPath, id: &SymlinkId ) -> Result<String, BackendError>

fn write_symlink( &self, _path: &RepoPath, target: &str ) -> Result<SymlinkId, BackendError>

fn root_commit_id(&self) -> &CommitId

fn root_change_id(&self) -> &ChangeId

fn empty_tree_id(&self) -> &TreeId

fn read_tree(&self, _path: &RepoPath, id: &TreeId) -> BackendResult<Tree>

fn write_tree(&self, _path: &RepoPath, tree: &Tree) -> BackendResult<TreeId>

fn read_conflict( &self, _path: &RepoPath, id: &ConflictId ) -> BackendResult<Conflict>

fn write_conflict( &self, _path: &RepoPath, conflict: &Conflict ) -> BackendResult<ConflictId>

fn read_commit(&self, id: &CommitId) -> BackendResult<Commit>

fn write_commit(&self, commit: Commit) -> BackendResult<(CommitId, Commit)>

Writes a commit and returns its ID and the commit itself. The commit should contain the data that was actually written, which may differ from the data passed in. For example, the backend may change the committer name to an authenticated user’s name, or the backend’s timestamps may have less precision than the millisecond precision in Commit.

impl Debug for LocalBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
