func Exchange

func Exchange(m *dns.Msg, edgeDNSServers []DNSServer) (msg *dns.Msg, err error)

func GetType

func GetType(v interface{}) string

func MergeAnnotations

func MergeAnnotations(target map[string]string, source map[string]string) map[string]string

MergeAnnotations adds or updates annotations from source to target and returns merge

func SplitAfter

func SplitAfter(s string, re *regexp.Regexp) (r []string)

SplitAfter works as the same way as strings.SplitAfter() but the separator is regexp
