The returned byte count includes space for tag information and any other additional space associated with serializing value. Args: value: Value we're serializing. field_number: Field number of this value. (Since the field number is stored as part of a varint-encoded tag, this has an impact on the total bytes required to serialize the value). field_type: The type of the field. One of the TYPE_* constants within FieldDescriptor. """
