pub fn sort(values: &ArrayRef, options: Option<SortOptions>) -> Result<ArrayRef>
Expand description
Sort the ArrayRef
using SortOptions
.
Performs a sort on values and indices. Nulls are ordered according
to the nulls_first
flag in options
. Floats are sorted using
IEEE 754 totalOrder
Returns an ArrowError::ComputeError(String)
if the array type is
either unsupported by sort_to_indices
or take
.
Note: this is an unstable_sort, meaning it may not preserve the order of equal elements.
Example
let array: ArrayRef = Arc::new(Int32Array::from(vec![5, 4, 3, 2, 1]));
let sorted_array = sort(&array, None).unwrap();
let sorted_array = sorted_array.as_any().downcast_ref::<Int32Array>().unwrap();
assert_eq!(sorted_array, &Int32Array::from(vec![1, 2, 3, 4, 5]));
