Failure while creating or verifying a logical snapshot.

Variants

Io(Error)

A filesystem operation failed.

Index

The materialized index could not be read.

Fields

source: Box<MaterializedIndexError>

Underlying index failure.

Invalid

Snapshot bytes violate the canonical format.

Fields

reason: &'static str

Stable diagnostic reason.

UnsupportedVersion

The snapshot was produced by a future disk format.

Fields

found: u16

Version found in the snapshot.

supported: u16

Version understood by this binary.

CheckpointConflict

A same-sequence snapshot exists for a different commit.

Fields

sequence: u64

Conflicting commit sequence.

FileLimitExceeded

Snapshot file length exceeds caller policy.

Fields

actual: u64

Observed file length.

maximum: u64

Configured maximum.

EntryLimitExceeded

Snapshot entry count exceeds caller policy.

Fields

actual: u64

Observed entry count.

maximum: u64

Configured maximum.

DecodedBytesLimitExceeded

Aggregate decoded entry bytes exceed caller policy.

Fields

maximum: u64

Configured maximum.

Trait Implementations

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl Display for SnapshotError

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

Formats the value using the given formatter.

impl Error for SnapshotError

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.
