Is there a way dynamically test an object (message) to determine if it has been serialized via MsgPack in python?
1 Answer
No: there is no magic or version number out of the box.
As stated by msgpack's author you have to do it on your side if needed:
MessagePack itself doesn't provide versioning in the format because applications need to build a protocol or file format that includes version description on top of it if they need to be self-describing about its format strictly.
