Trait deltalake::datafusion::parquet::record::RecordReader

pub trait RecordReader<T> {
    // Required method
    fn read_from_row_group(
        &mut self,
        row_group_reader: &mut dyn RowGroupReader,
        num_records: usize
    ) -> Result<(), ParquetError>;
}

read up to max_records records from row_group_reader into self The type parameter T is used to work around the rust orphan rule when implementing on types such as Vec<T>.
