Module filter_projection 

Filter and projection transform.

Filtering

Zero or more FilterRules can be configured. When filters is empty every event passes through. When multiple rules are present they are combined according to FilterMode:

• FilterMode::All (default) — AND semantics: every rule must match.
• FilterMode::Any — OR semantics: at least one rule must match.

Column projection

Either include_columns or exclude_columns may be set (not both). Setting both is rejected at FilterProjectionTransform::new time.
