}

Errors that can occur while reading or writing pack files.

Variants

InvalidMagic(String)

A .pack file did not start with the SPCK magic.

UnsupportedVersion(u32)

The pack version is newer than this build supports.

InvalidIndexMagic(String)

An .idx file did not start with the SIDX magic.

BlobNotFound(String)

The digest is not present in this pack.

Io(Error)

An underlying filesystem operation failed.

CompressionError(String)

Zstd compression failed while writing the pack.

DecompressionError(String)

Zstd decompression failed while reading the pack.

EmptyPack

At least one object is required to create a pack.

UnexpectedObjectType(u8)

An object record used a type byte this build does not know.

HashMismatch

The blob read from the pack did not match its recorded digest.

Fields

expected: String

The digest the object was addressed by.

actual: String

The digest of what was actually read.

Trait Implementations

impl Debug for PackError

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

Formats the value using the given formatter.

impl Display for PackError

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

Formats the value using the given formatter.

impl Error for PackError

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 PackError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PackError> for CasError

fn from(source: PackError) -> Self

Converts to this type from the input type.
