[JsBsonRPCSerializable] C++에서 객체 bson Serialize및 json변환 라이브러리

라이브러리 소스 : https://github.com/jc-lab/JsBsonRPCSerializable

테스트 VS프로젝트 : https://github.com/jc-lab/JsBsonRPCSerializable-testproject

JsBsonRPCSerializable는 C++ 에서 객체를 Serialize/Deserialze 할 수 있게 도와주는 라이브러리 입니다.

Serialize 형식은 Bson 형식을 따르며, JSONObjectMapper 클래스를 통해 json(rapidjson)변환 기능도 지원합니다.
