Function SortSlices

cmp/cmpopts/sort.go:36–43

SortSlices returns a [cmp.Transformer] option that sorts all []V. The lessOrCompareFunc function must be either a less function of the form "func(T, T) bool" or a compare function of the format "func(T, T) int" which is used to sort any slice with element type V that is assignable to T. A less func
