Errors returned while selecting and claiming a batch of events.

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.

CounterOverflow

The delivery attempt counter cannot be incremented safely.

Fields

row_id: RowId

The event row whose attempt count overflowed.

EntropyUnavailable

The operating system could not provide claim-token entropy.

Fields

source: Error

The underlying entropy-provider error.

Serialization

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

Fields

detail: String

Details describing the invalid stored value.

MigrationMismatch

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

Fields

detail: String

Details identifying the incompatible schema contract.

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 ClaimError

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

Formats the value using the given formatter.

impl Display for ClaimError

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

Formats the value using the given formatter.

impl Error for ClaimError

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.
