Function canSortSimply

internal/spew/common.go:256–275

canSortSimply tests whether a reflect.Kind is a primitive that can be sorted directly, or whether it should be considered for sorting by surrogate keys (if the ConfigState allows it).

(kind reflect.Kind)

// directly, or whether it should be considered for sorting by surrogate keys
// (if the ConfigState allows it).
func canSortSimply(kind reflect.Kind) bool {
	// This switch parallels valueSortLess, except for the default case.
