Enum OnError

Source

pub enum OnError {
    Skip,
    Null,
    Drop,
}

Expand description

Behavior when an enricher fails (timeout, fetch error, parse error, …).

Applied per enricher. Defaults to OnError::Skip so a single failed enrichment never breaks the result stream.

Variants§

§

Skip

Deliver the result unenriched for this field. Default. Logs a warning.

§

Null

Inject null under inject_field so downstream consumers see a “we tried” marker rather than missing-field ambiguity.

§

Drop

Suppress the result entirely before serialization. Useful for dedup / pre-filter style enrichers that intentionally drop matches based on external context.
