amsgpack 0.0.9

Another MessagePack library

amsgpack - Python Message Pack module

C library for python 3.10+.

Why:

• I couldn't negotiate adding type hints to msgpack-python
• I couldn't negotiate adding Unpacker to ormsgpack
• There's no stream unpacking in msgspec
• I couldn't find another MessagePack library
• msgpack-python interfaces are messy and the library is a bit slow

Installation

pip install amsgpack

Examples

>>> from amsgpack import packb, unpackb
>>> packb({"compact": True, "schema": 0})
b'\x82\xa7compact\xc3\xa6schema\x00'
>>> unpackb(b'\x82\xa7compact\xc3\xa6schema\x00')
{'compact': True, 'schema': 0}

>>> from amsgpack import FileUnpacker
>>> from io import BytesIO
>>> for data in FileUnpacker(BytesIO(b'\x00\x01\x02')):
...     print(data)
...

>>> from amsgpack import Unpacker
>>> unpacker = Unpacker()
>>> unpacker.feed(b'\x82\xa7compact\xc3\xa6schema\x00')
>>> next(unpacker)
{'compact': True, 'schema': 0}
