Errors raised while turning configuration into live data connections.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Config(ConfigError)

A configuration error surfaced while building a resource. Its category and code delegate to the underlying ConfigError.

UnsupportedSystem(DbSystem)

The configured database system has no connector in this build.

UnsupportedCacheBackend(CacheBackend)

The configured cache backend has no connector in this build.

UnsupportedMessagingBackend(MessagingBackend)

The configured messaging backend has no connector in this build.

MissingUrl(&'static str)

No connection URL could be derived from the provided configuration.

Messaging(String)

A messaging client failed to set up or connect.

Outbox(String)

The transactional outbox encountered an error.

Idempotency(String)

The idempotency store encountered an error.

Migration(String)

A schema migration failed or is invalid (e.g. a duplicate version).

LockHeld(String)

A named distributed lock is already held by another holder.

FeatureDisabled(&'static str)

The requested backend needs a cargo feature that is not enabled.

Io(Error)

An underlying I/O error.

Sqlx(Error)

A SQL driver error (sql feature).

Redis(RedisError)

A Redis client error (redis feature).

Nats(ConnectError)

A NATS connection error (nats feature).

RabbitMq(Error)

A RabbitMQ connection error (rabbitmq feature).

Kafka(Error)

A Kafka connection error (kafka feature).

Storage(Error)

An object-storage error (storage feature).

InvalidPage(String)

A pagination request was malformed (e.g. an out-of-range page size).

InvalidCursor(String)

A pagination cursor was invalid or could not be decoded.

Trait Implementations

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl DomainError for DataError

fn category(&self) -> ErrorCategory

The coarse classification of this error.

fn code(&self) -> ErrorCode

The stable domain.reason code for this error.

fn is_retryable(&self) -> bool

Whether retrying might help. Defaults to the category’s policy.

fn http_status(&self) -> u16

The HTTP status to surface. Defaults to the category’s status.

impl Error for DataError

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
