Errors returned by fenced post-claim mutations.

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.

NotFound

The requested event row does not exist.

IllegalTransition

The current delivery state cannot perform this mutation.

Fields

state: DeliveryState

The delivery state that rejected the mutation.

LostClaim

The claim token is stale or the lease has expired.

MigrationMismatch

The installed schema does not satisfy this adapter’s migration contract.

Fields

detail: String

Details identifying the incompatible schema contract.

Serialization

A database value could not be reconstructed as a valid domain value.

Fields

detail: String

Details describing the invalid stored value.

Sql

A non-transient SQL operation failed.

Fields

operation: &'static str

The adapter operation that failed.

source: Error

The underlying SQLx error.

Transient

A SQL operation failed with a retryable PostgreSQL condition.

Fields

operation: &'static str

The adapter operation that failed.

kind: TransientKind

The retryable PostgreSQL failure category.

source: Error

The underlying SQLx error.

Trait Implementations

impl Debug for MutationError

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

Formats the value using the given formatter.

impl Display for MutationError

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

Formats the value using the given formatter.

impl Error for MutationError

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.
