Flatbuffers

FlatBuffers is a cross platform serialization library architected for maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility. It was originally created at Google for game development and other performance-critical applications.
