Function arrow_ord::sort::lexsort_to_indices
source · pub fn lexsort_to_indices(
columns: &[SortColumn],
limit: Option<usize>
) -> Result<UInt32Array, ArrowError>
Expand description
Sort elements lexicographically from a list of ArrayRef
into an unsigned integer
(UInt32Array
) of indices.
Note: for multi-column sorts without a limit, using the row format may be significantly faster
