Enum StoreError 

pub enum StoreError {
    Io(Arc<Error>),
    Corruption(String),
    NotFound,
    AlreadyExists,
    TxnConflict,
    ReadOnly,
    Timeout,
    CapacityExceeded,
    CasMismatch,
    KeyNotFound,
    Unsupported(String),
    Other(String),
}

Errors that can be returned by any OxiStore backend.

Variants

Io(Arc<Error>)

An I/O error occurred at the file-system level.

Corruption(String)

The database file is corrupt or in an unrecognized format.

NotFound

The requested key was not found (used when absence is treated as error).

AlreadyExists

A key was inserted but already exists (reserved for unique-insert APIs).

TxnConflict

A write transaction conflicted with a concurrent transaction and must be retried.

ReadOnly

The store is open in read-only mode and does not accept writes.

Timeout

An operation timed out.

CapacityExceeded

A bounded store or cache has exceeded its capacity limit.

CasMismatch

A compare-and-swap operation failed because the expected value did not match the current stored value.

KeyNotFound

The requested key was not found in the store.

Unsupported(String)

The operation is not supported by this backend or configuration.

Other(String)

Any other backend-specific error.

Trait Implementations

impl Clone for StoreError

fn clone(&self) -> StoreError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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 StoreError

fn from(e: Error) -> StoreError

Converts to this type from the input type.

impl From<String> for StoreError

fn from(s: String) -> StoreError

Converts to this type from the input type.
