Expand description

An enum wrapper for all arrow builder types that we support. Used to store a builder for each column and avoid dynamic dispatch and downcasting when appending data.

Variants§

§

ListBuilder(Box<ListBuilder<ArrowColumn>>)

ListBuilder & MapBuilder are handled separately than other builder types since they uses generic parameters for the inner types, and are boxed to avoid recursive type definitions.

§

MapBuilder(Box<MapBuilder<StringBuilder, ArrowColumn>>)

§

StructBuilder(StructBuilder)

StructBuilder is handled separately since its append_null() method must be overriden to both append nulls to all field builders and to append a null to the struct. It’s unclear why arrow-rs implemented this differently than ListBuilder and MapBuilder.
