Errors raised by this module.

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.

InvalidRefName(String)

name failed validate_ref_name_grammar.

RefNameTooLong

A new ref’s name is over its kind’s bound: MAX_REF_NAME_BYTES for a ref name, MAX_BRANCH_NAME_BYTES for a branch and MAX_TAG_NAME_BYTES for a tag (SPEC-REFS §3).

Fields

name: String

The name.

len: usize

Its length in bytes.

kind: RefNameKind

Which bound it broke.

InvalidRef(String)

On-disk bytes were not a valid 65-byte ref wire (length wrong, uppercase hex, non-hex byte, etc.).

InvalidHead

HEAD content was neither a valid symbolic ref nor a valid detached hash.

NoHead

HEAD is missing.

Conflict(String)

CAS condition failed: ref does not match expected state.

NotFound(String)

Tried to delete a ref that does not exist.

CurrentBranch(String)

Tried to delete the branch HEAD currently points to.

Io(Error)

Underlying I/O failure.

RefBatchLengthMismatch

A list_refs_with-style batch callback returned a different number of outcomes than candidates it was given — the caller’s contract violation, not a clean exit-coded error, but caught here rather than silently desyncing names from hashes.

Fields

expected: usize

actual: usize

Trait Implementations

impl Debug for RefError

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

Formats the value using the given formatter.

impl Display for RefError

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

Formats the value using the given formatter.

impl Error for RefError

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.
