Types

type Replacer

type Replacer struct {
	// contains filtered or unexported fields
}

Replacer replaces labels for values in strings.

func New

func New() Replacer

New makes a new replacer. This only needs to be called once in the setup and then call Replace for each incoming message. A replacer is safe for concurrent use.

func (Replacer) Replace

func (r Replacer) Replace(ctx context.Context, state request.Request, rr *dnstest.Recorder, s string) string

Replace performs a replacement of values on s and returns the string with the replaced values.
