Function hostport

logger/pattern.go:284–290

hostport is a simplified no-alloc version of net.SplitHostPort. Since we know that the address values have the correct form we can skip all the error checking.

(s string)

// address values have the correct form we can
// skip all the error checking.
func hostport(s string) (host, port string) {
	if s == "" {
		return "", ""
	}
	n := strings.LastIndexByte(s, ':')
	return s[:n], s[n+1:]
}

// atoi is a replacement for strconv.Atoi/strconv.FormatInt
// which does not alloc.
