Storage-specific error type

Variants

IoError(Error)

Disk I/O failures during log/snapshot operations

PathError

Custom error with a path as a string slice (&str)

Fields

path: PathBuf

source: Error

BincodeError(Box<ErrorKind>)

Serialization failures for persisted data

StateMachineError(String)

State machine application errors

LogStorage(String)

Log storage subsystem failures

DataCorruption

Checksum validation failures

Fields

location: String

ConfigStorage(String)

Configuration storage failures

DbError(String)

Embedded database errors

Convert(ConvertError)

Error type for value conversion operations

File(FileError)

File errors

SerializationError(String)

Serialization error

IdAllocation(IdAllocationError)

ID allocation errors

FeatureNotEnabled(String)

Feature not enabled in configuration

Returned when client requests a feature (e.g., TTL) that is not enabled in the server configuration. This prevents silent failures and ensures explicit feature activation.

NotServing(String)

State machine not serving requests

Returned when read operations are attempted during critical operations such as snapshot restoration. This ensures reads never access inconsistent or temporary state during database transitions.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
