Errors returned by the index subsystem.

Variants

BadMagic

Magic bytes were not "MKIX".

UnsupportedVersion(u8)

version byte was not the current FORMAT_VERSION.

BadStatus(u8)

Status byte was outside the documented {0x00..=0x04} range.

Corrupt

Truncated or otherwise malformed entry.

TooLarge

File exceeded MAX_INDEX_BYTES.

InvalidPath(String)

Path failed validate_index_path.

DuplicatePath(String)

Path appeared more than once in the same index.

RemovedHasHash(String)

A Removed entry carried a nonzero object_hash (SPEC-INDEX §3 requires the all-zero hash for removals).

InvalidPathEncoding

Path UTF-8 decoding failed.

Io(Error)

Underlying I/O failure.

Store(StoreError)

Object store lookup/decoding failed while deriving an index from a tree.

NotTree

A tree walk found a non-tree object where a tree hash was expected.

TreeTooDeep

A tree walk exceeded MAX_TREE_DEPTH nesting levels — likely a crafted untrusted repo trying to overflow the native stack.

Trait Implementations

impl Debug for IndexError

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

Formats the value using the given formatter.

impl Display for IndexError

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

Formats the value using the given formatter.

impl Error for IndexError

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.
