// This package contains hand-coded set implementations that should be similar
// to the autogenerated ones in pkg/util/sets.
// We can't simply use net.IPNet as a map-key in Go (because it contains a
// []byte).
// We could use the same workaround we use here (a string representation as the
// key) to autogenerate sets. If we do that, or decide on an alternate
// approach, we should replace the implementations in this package with the
// autogenerated versions.
// It is expected that callers will alias this import as "netsets" i.e. import
// netsets "k8s.io/kubernetes/pkg/util/net/sets"
