Function ExampleOption_sortedSlice

cmp/example_test.go:198–218

Two slices may be considered equal if they have the same elements, regardless of the order that they appear in. Transformations can be used to sort the slice. This example is for demonstrative purposes; use [github.com/google/go-cmp/cmp/cmpopts.SortSlices] instead.
