Failure from local storage, remote transport, validation, or optimistic concurrency.

Variants

EmptyContent

Content is empty after trimming.

ContentTooLarge

One record exceeds its byte bound.

Fields

maximum_bytes: usize

Configured maximum bytes per record.

QueryTooLarge

A scan query exceeds its byte bound.

Fields

maximum_bytes: usize

Configured maximum query bytes.

RecordCapacity

The record-count bound is exhausted.

Fields

maximum: usize

Configured maximum records.

ContentCapacity

The aggregate content-byte bound is exhausted.

Fields

maximum_bytes: usize

Configured maximum aggregate bytes.

StorageCapacity

The backing store reached its configured storage bound.

SecretRejected

Content was rejected as a likely credential or secret.

Duplicate

Equivalent normalized content already exists.

NotFound

The requested record does not exist.

Conflict

A key version or snapshot state is stale.

RemoteReadOnly

A mutation targeted a namespace not owned by this backend.

InvalidPagination

A store returned an invalid or unbounded pagination sequence.

UnsupportedSchemaVersion

Database schema is newer than this implementation supports.

Fields

found: i64

Schema version found on disk.

supported: i64

Newest schema supported by this implementation.

Backend

A backend-specific operation failed.

Fields

source: Box<dyn Error + Send + Sync>

Backend-specific failure.

Unavailable

A backend-specific operation failed transiently and may be retried.

Fields

source: Box<dyn Error + Send + Sync>

Backend-specific transient failure.

Implementations

impl MemoryError

pub fn backend(source: impl Error + Send + Sync + 'static) -> Self

Wraps a permanent or unclassified backend-specific failure.

pub fn unavailable(source: impl Error + Send + Sync + 'static) -> Self

Wraps a transient backend-specific failure that may succeed when retried.

pub fn is_retryable(&self) -> bool

Returns whether the backend classified this failure as transient.

Trait Implementations

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl Error for MemoryError

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<RemoteClientError> for MemoryError

Available on crate feature client only.

fn from(source: RemoteClientError) -> Self

Converts to this type from the input type.
