def initialize(string)
  # A label is limited to 63 octets. [RFC 1035 2.3.4] Checking it here
  # makes it an invariant of the object: every label, however it was
  # built, fits in its length octet and cannot wrap it. Callers turn
  # this into the error their own contract promises.
  if string.bytesize > 63
    raise ArgumentError, "DNS label is too long (#{string.bytesize} bytes, max 63): #{string.inspect}"

  # case insensivity of DNS labels doesn't apply non-ASCII characters. [RFC 4343]
  # This assumes @string is given in ASCII compatible encoding.
