Enum Error 

#[non_exhaustive]
pub enum Error {
    NotARepository(PathBuf),
    WorktreeNotFound(PathBuf),
    Io(Error),
    Vcs(Error),
}

An error from a Repo operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotARepository(PathBuf)

Repo::open found no .git/.jj from the start dir up to the filesystem root.

WorktreeNotFound(PathBuf)

A worktree/workspace lookup by path matched no attached worktree.

Io(Error)

A filesystem operation failed (e.g. removing a workspace directory).

Vcs(Error)

An underlying vcs-git / vcs-jj (i.e. processkit) error.

Implementations

impl Error

pub fn is_merge_conflict(&self) -> bool

Whether this wraps a merge/rebase conflict from the backend — so a caller can branch on “conflict, resolve it” vs. a hard failure without matching on processkit::Error internals. (Recognises git’s conflict markers; jj surfaces conflicts as state, not errors — see Repo::in_progress_state.)

Named to match the wrapper classifiers (vcs_cli_support::is_merge_conflict) — one name per concept across the workspace.

pub fn is_nothing_to_commit(&self) -> bool

Whether this is a benign “nothing to commit” — an empty commit attempt the caller likely wants to treat as a no-op.

pub fn is_transient_fetch_error(&self) -> bool

Whether this is a transient fetch/network failure worth retrying (DNS, connection reset, timeout). The underlying clients already retry their own fetches; this is for retrying higher-level flows.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self
