Variants

Io

Filesystem operation failed for a named path.

Fields

path: PathBuf

Path involved in the operation.

source: Error

Underlying platform error.

Format(FormatError)

Framing, version, length, or checksum validation failed.

Decode(String)

Hand-written payload decoding rejected malformed bytes.

GraphUnsupportedBuild

This build cannot open a v3 manifest containing graph state.

AheadOfLog

Snapshot log sequence exceeds the durable WAL end.

Fields

snapshot: u64

Sequence covered by the snapshot.

durable: u64

Sequence known durable in the WAL.

Segment(SegmentError)

A referenced segment header failed validation.

UnknownEpochAlias

The published alias did not name a registry entry.

Fields

alias: EpochIdentity

Rejected alias.

UnknownSegmentEpoch

A segment epoch tag did not name any registry entry.

Fields

segment: SegmentId

Segment carrying the bad tag.

epoch: EpochId

Rejected embedding epoch id.

Trait Implementations

impl Debug for ManifestError

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

Formats the value using the given formatter.

impl Display for ManifestError

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

Formats the value using the given formatter.

impl Error for ManifestError

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<FormatError> for ManifestError

fn from(error: FormatError) -> Self

Converts to this type from the input type.

impl From<SegmentError> for ManifestError

fn from(error: SegmentError) -> Self

Converts to this type from the input type.
