Errors that can occur during event store operations.

Variants

ConcurrencyConflict

Optimistic concurrency conflict.

Fields

aggregate_id: String

expected: i64

actual: i64

AggregateNotFound

Fields

aggregate_id: String

InvalidSequence

Fields

aggregate_id: String

expected: i64

actual: i64

InvalidAudit

One or more events in an append batch had invalid audit metadata. Defense-in-depth: the bus should have caught this first.

Fields

aggregate_id: String

event_index: usize

source: AuditError

Integrity

Stored event signatures are missing or do not match the recomputed integrity chain.

Fields

source: IntegrityError

DatabaseError

Fields

message: String

SerializationError

Fields

message: String

IoError(Error)

Unsupported

The store does not implement snapshot persistence. Callers fall back to replaying the full event stream.

Other

Fields

message: String

Implementations

impl EventStoreError

pub fn database(message: impl Into<String>) -> Self

pub fn serialization(message: impl Into<String>) -> Self

pub fn other(message: impl Into<String>) -> Self

pub fn invalid_audit( aggregate_id: impl Into<String>, event_index: usize, source: AuditError, ) -> Self

Trait Implementations

impl Debug for EventStoreError

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

Formats the value using the given formatter.

impl Display for EventStoreError

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

Formats the value using the given formatter.

impl Error for EventStoreError

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 EventStoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<IntegrityError> for EventStoreError

fn from(source: IntegrityError) -> Self

Converts to this type from the input type.
