Enum EngineError 

#[non_exhaustive]
pub enum EngineError {
    Source(SourceError),
    Sink(SinkError),
    Queue(QueueError),
    Task(String),
    DocumentsRejected(usize, String),
}

A fatal error that stops the sync run. Because the engine confirms a change’s source ack only after the change is durably applied, stopping on an error is safe: unconfirmed changes are redelivered when the run restarts.

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.

Source(SourceError)

From the source — capturing changes or resolving/assembling documents.

Sink(SinkError)

From a sink write.

Queue(QueueError)

From the work queue.

Task(String)

A spawned task failed to join (panicked).

DocumentsRejected(usize, String)

The sink rejected one or more documents at the item level and the failure policy is Stop. Switch to skip to quarantine such documents and keep the pipeline running.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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.
