Enum StorageError 

pub enum StorageError {
    InitializationError(String),
    WriteError(String),
    QueryError(String),
    DiskFullError(String),
    CorruptionError(String),
    PermissionError(String),
    ConfigError(String),
    PurgeError(String),
    DatabaseError(String),
    IoError(String),
    SerializationError(String),
}

Generic storage errors returned by StorageBackend implementations.

All variants carry string payloads so this type has no dependency on any database library. Backend-specific error types should convert to these via a From impl.

Variants

InitializationError(String)

Storage initialization failed.

WriteError(String)

Write operation failed.

QueryError(String)

Query operation failed.

DiskFullError(String)

Disk is full or insufficient space.

CorruptionError(String)

Storage corruption detected.

PermissionError(String)

Permission denied.

ConfigError(String)

Configuration error.

PurgeError(String)

Purge operation failed.

DatabaseError(String)

Underlying database error (string representation).

IoError(String)

I/O error (string representation).

SerializationError(String)

Serialization error (string representation).

Implementations

impl StorageError

pub fn is_recoverable(&self) -> bool

pub fn is_corruption(&self) -> bool

pub fn is_disk_full(&self) -> bool

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.

impl From<StorageError> for StorageError

fn from(e: StorageError) -> Self

Converts to this type from the input type.
