Expand description

What a merge does with each kind of row.

Fields§

§matched: Matched

What happens to a table row whose key a source row has.

§columns: Option<Vec<String>>

The columns a match changes; every source column but the keys when absent.

§not_matched: NotMatched

What happens to a source row whose key no table row has.

§not_matched_by_source: BySource
