pub enum StorageError {
    Open(String),
    NotFound(String),
    TableNotFound(String),
    KeyNotFound,
    Transaction(String),
    ReadOnly,
    Conflict(String),

}

Errors that can occur in storage operations.

This enum covers all possible failure modes for storage backends, from database-level issues to transaction and I/O errors.

Variants

Open(String)

The database could not be opened or created.

NotFound(String)

The database file or directory does not exist.

TableNotFound(String)

A table does not exist.

KeyNotFound

A key was not found in the table.

Transaction(String)

A transaction error occurred (failed to begin, commit, or rollback).

ReadOnly

Attempted a write operation on a read-only transaction.

Conflict(String)

A conflict occurred due to concurrent modification.

Corruption(String)

The database is corrupted.

Io(Error)

An I/O error occurred.

Serialization(String)

A serialization or deserialization error occurred.

StorageFull(String)

The storage is full or a size limit was exceeded.

InvalidArgument(String)

An invalid argument was provided.

Unsupported(String)

The operation is not supported by this backend.

Internal(String)

An internal error occurred in the storage backend.

Implementations

impl StorageError

pub const fn is_recoverable(&self) -> bool

Returns true if this error is recoverable.

Recoverable errors include transient conditions like conflicts that may succeed on retry. Non-recoverable errors include corruption and configuration issues.

pub const fn is_not_found(&self) -> bool

Returns true if this is a “not found” type error.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

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<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.
