docs: Returns the number of consecutive trailing one or zero bits.
  If network is true, returns the number of consecutive trailing zero bits.
  Otherwise, returns the number of consecutive trailing one bits.
  <p>
  This method applies only to the lower value of the range if this segment represents multiple values.
