Struct DefaultGeoStatsAccumulatorFactory

pub struct DefaultGeoStatsAccumulatorFactory {}

Default accumulator for GeospatialStatistics

When this crate is built with geospatial support, this factory constructs a [ParquetGeoStatsAccumulator] that ensures Geometry columns are written with statistics when statistics for that column are enabled. Otherwise, this factory returns a VoidGeoStatsAccumulator that never adds any geospatial statistics.

Bounding for Geography columns is not currently implemented by parquet-geospatial and this factory will always return a VoidGeoStatsAccumulator.
