Struct StripeRowIndex 

pub struct StripeRowIndex { /* private fields */ }

Row indexes for all columns in a stripe

This structure provides access to row group statistics for all primitive columns in a stripe, enabling row group-level filtering.

Implementations

impl StripeRowIndex

pub fn new( columns: HashMap<usize, RowGroupIndex>, total_rows: usize, rows_per_group: usize, ) -> Self

pub fn column(&self, column_idx: usize) -> Option<&RowGroupIndex>

Get the row group index for a column

pub fn num_row_groups(&self) -> usize

Get the number of row groups in this stripe

pub fn row_group_stats( &self, column_idx: usize, row_group_idx: usize, ) -> Option<&ColumnStatistics>

Get statistics for a specific row group and column

pub fn total_rows(&self) -> usize

Get the total number of rows in this stripe

pub fn rows_per_group(&self) -> usize

Get the number of rows per row group

pub fn column_indices(&self) -> impl Iterator<Item = usize> + '_

Get an iterator over all column indices that have row indexes
