Errors that can occur during CAS operations.

Variants

BlobNotFound(String)

The requested blob does not exist in the store (loose or packed).

HashMismatch

The stored bytes did not hash to the requested address.

Fields

expected: String

The hash the blob was addressed by.

actual: String

The hash of what was actually read back.

LockPoisoned(String)

A mutex protecting interior cache state was poisoned.

Io(Error)

An underlying filesystem operation failed.

CompressionError(String)

Zstd compression failed (requires the zstd feature).

DecompressionError(String)

Zstd decompression failed (requires the zstd feature).

DecompressionTooLarge

Decompressed data exceeded the configured safety limit (zip-bomb protection).

Fields

max: usize

The maximum accepted decompressed size in bytes.

AlreadyExists(String)

crate::store::BlobStore::put_blob_new was called for an existing blob.

InvalidPath(String)

A derived path was not usable (e.g. malformed hex on disk).

Pack(PackError)

A packfile operation failed.

GcPathEscape(String)

A garbage-collection sweep was asked to trash or delete a path outside the store root (internal invariant violation).

TaskJoin(String)

A spawn_blocking task joined by an async GC wrapper panicked or the tokio runtime was already shut down (requires the tokio feature).

Trait Implementations

impl Debug for CasError

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

Formats the value using the given formatter.

impl Display for CasError

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

Formats the value using the given formatter.

impl Error for CasError

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 CasError

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.
