Enum EventStoreError 

pub enum EventStoreError {
    Validation(String),
    IdempotencyConflict(String),
    ExpectedCursorConflict(String),
    CursorExpired(String),
    Integrity(String),
    Io(String),
    Serialization(String),
}

Errors returned by canonical event store implementations.

Variants

Validation(String)

The provided input violates the event-store contract.

IdempotencyConflict(String)

The idempotency identity already exists with different append input.

ExpectedCursorConflict(String)

The caller supplied an expected cursor that does not match storage state.

CursorExpired(String)

The requested cursor is outside the retained history.

Integrity(String)

Storage history is missing data that should still be retained.

Io(String)

An I/O error occurred.

Serialization(String)

A serialization or deserialization error occurred.

Trait Implementations

impl Clone for EventStoreError

fn clone(&self) -> EventStoreError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EventStoreError

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

Formats the value using the given formatter.

impl Display for EventStoreError

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

Formats the value using the given formatter.

impl Eq for EventStoreError

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<EventStoreError> for CommitError

fn from(source: EventStoreError) -> CommitError

Converts to this type from the input type.

impl PartialEq for EventStoreError

fn eq(&self, other: &EventStoreError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
