Enum RemoteError 

pub enum RemoteError {
    Transport(TransportError),
    Validation(ValidationError),
    BreakerOpen(CircuitBreakerOpenError),
    Internal(DataFusionError),
}

A failure anywhere on the remote call path.

This is the single error the remote layer threads through the exchange: transport failures, response-containment failures (including the streaming size ceiling and the per-call timeout), a fast-fail when the breaker is open, and internal bridging errors. It converts to a DataFusionError at the UDF trait boundary.

Variants

Transport(TransportError)

A transport/RPC-layer failure.

Validation(ValidationError)

A response-containment failure (schema, row count, size, or timeout).

BreakerOpen(CircuitBreakerOpenError)

The call was rejected because the circuit breaker is open.

Internal(DataFusionError)

An internal error (batch construction or the arrow bridge).

Implementations

impl RemoteError

pub fn metric_reason(&self) -> String

A short, stable reason string for metrics keying.

Trait Implementations

impl Debug for RemoteError

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

Formats the value using the given formatter.

impl Display for RemoteError

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

Formats the value using the given formatter.

impl Error for RemoteError

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.
