Expand description
Wrapper struct to specify sort order
Fields§
§column_idx: i32
The column index (in this row group) *
descending: bool
If true, indicates this column is sorted in descending order. *
nulls_first: bool
If true, nulls will come before non-null values, otherwise, nulls go at the end.
