CW Msgpack Coder

Introduction

Simple pure Python object encoder and decoder using msgpack (u-msgpack-python package at bottom).

It allows encode Python object with high speed and compression since we using msgpack at bottom.

It reduce code overhead to minimum and allow you focus on algorithms.

How to use it

It is very simple:

from cw_msgpack_coder.umsgpack_coder import UmsgpackCoder


class YourNestedClass:
    pass


class YourClass:
    def __init__(name, nested)
        self.name = name
        self.nested = nested


# create coder
coder = UmsgpackCoder()

# register your classes (required because of security reasons)
coder.set_default_coder_for_class(self.YourClass)
coder.set_default_coder_for_class(self.YourNestedClass)

# register old modules names (required if you renamed some modules and want load old data)
coder.set_set_old_module_name_to_current('old_name', 'current_name')

# now create some objects to test
o = YourClass('hello world!', YourNestedClass())

# encode to bytes
encoded = coder.dumps(o)

# decode bytes to objects
o2 = coder.decode(encoded)

# o == o2!
