type Replacer

type Replacer interface {
	Replace(string) string
	Set(key, value string)
}

Replacer is a type which can replace placeholder substrings in a string with actual values from a dns.Msg and responseRecorder. Always use NewReplacer to get one of these.

func New

func New(r *dns.Msg, rr *dnstest.Recorder, emptyValue string) Replacer

New makes a new replacer based on r and rr. Do not create a new replacer until r and rr have all the needed values, because this function copies those values into the replacer. rr may be nil if it is not available. emptyValue should be the string that is used in place of empty string (can still be empty string).
