Users will + * mainly need to implement four functions as follows: + * - GetFunction. It is used to get the packed function from the json runtime + * module using a provided function name. This function returns a PackedFunc + * that can be directly invoked by feeding it with parameters. + * - SaveToBinary. This function is used to achieve the serialization purpose. + * The emitted binary stream can be directly saved to disk so that users can + * load then back when needed. + * - LoadFromFile. This is a static function that acts as a helper to create Review comment: LoadFromFile is not necessary, as not all runtime has a json format. We should emphasize that although we use json as storage format, the example works for all other serialization formats ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
