Enum Error 

pub enum Error {
    NotARepo(PathBuf),
    CasConflict {
        refname: String,
        expected: Option<Oid>,
        found: Option<Oid>,

}

Errors from the git write substrate.

Variants

NotARepo(PathBuf)

The vault root is not a git repository (feature is git-gated).

CasConflict

A compare-and-swap on a ref failed: the ref moved since we read it. The changeset applied nothing; the caller should re-read and retry or surface a conflict (the reconsideration domino).

Fields

refname: String

expected: Option<Oid>

found: Option<Oid>

PreconditionFailed

A per-file precondition failed: the blob at path in the base tree is not what the caller read (it changed underneath the changeset). The whole changeset aborts with nothing applied — the multi-file CAS / the reconsideration domino. The caller re-reads the affected paths and re-decides.

Fields

path: String

expected: Option<Oid>

found: Option<Oid>

Git(Error)

Underlying libgit2 error.

Io(Error)

Filesystem error (working-tree materialization, etc.).

Other(String)

Invariant violation or unsupported state with a description.

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, __formatter: &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(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
