Function JoinTo

util.go:26–40

JoinTo writes the given slice of values delimited by the provided delimiter to the given SafeWriter.

(w SafeWriter, delim RedactableString, values interface{})

// JoinTo writes the given slice of values delimited by the provided
// delimiter to the given SafeWriter.
func JoinTo(w SafeWriter, delim RedactableString, values interface{}) {
	// Ideally, we'd make the interface clearer: JoinTo is a generic function,
	// with a "values" argument of type []T where T is a type variable.
	v := reflect.ValueOf(values)
	if v.Kind() != reflect.Slice {
		// Note a slice: just print the value as-is.
		w.Print(values)
	}
	for i, l := 0, v.Len(); i < l; i++ {
		if i > 0 {
			w.Print(delim)
		}
		w.Print(v.Index(i).Interface())

// Join creates a redactable string from the
