Enum SidecarError 

pub enum SidecarError {
    Connector(String),
    Join(String),
    WatermarkStore(String),
    Other(String),
}

Errors produced by the sidecar CDC consumer and its dependencies.

Variants

Connector(String)

An error returned by the underlying connector_arrow query layer (e.g. SQL syntax error, connection failure, schema mismatch).

Join(String)

A Tokio spawn_blocking task was dropped before it could produce a result, typically because the runtime is shutting down.

WatermarkStore(String)

A crate::WatermarkStore operation (load or save) failed.

When raised by crate::TimestampCdcConsumer::try_with_watermark_store at construction time it indicates a corrupt or inaccessible store. When raised during a poll cycle the consumer rolls back its in-memory watermark so the same rows will be re-fetched on the next poll.

Other(String)

A catch-all variant for errors that do not fit the other categories.

Trait Implementations

impl Debug for SidecarError

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

Formats the value using the given formatter.

impl Display for SidecarError

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

Formats the value using the given formatter.

impl Error for SidecarError

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<ConnectorError> for SidecarError

fn from(e: ConnectorError) -> Self

Converts to this type from the input type.
