  data.to_str
end

.parse(str_data, &block) ⇒ Hash, ...

Parses a string or data object and converts it in data structure.

TODO: support options like the C Ruby module does

Parameters:

  • str_data (String, NSData) —

    the string or data to serialize.

Returns:

  • (Hash, Array, NilClass) —

    the converted data structure, nil if the incoming string isn’t valid.

Raises:

  • (ParserError) —

    If the parsing of the passed string/data isn’t valid.
