> But I didn't find a method to access the ..exact flags in StatisticsConverter, so my plan is to first add functions similar to row_group_mins to the converter to extract the flags, which requires a change to arrow-rs first, and then collect and pass the extracted boolean array of flags to get_col_stats to decide which one to use, Precision::Exact and Precision::InExact. I think the first thing that is needed in arrow-rs is to expose the [`is_max_value_exact`](https://docs.rs/parquet/latest/parquet/format/struct.Statistics.html#structfield.is_max_value_exact) and `is_min_value_exact` fields into the corresponding Rust structs (`ValueStatistics`): https://docs.rs/parquet/latest/parquet/file/statistics/enum.Statistics.html https://docs.rs/parquet/latest/parquet/file/statistics/struct.ValueStatistics.html -- This is an automated message from the Apache Git Service.
