FS message packer
Project description
FS Message packer
Introduction
Message packer for socket communications.
Pure-Python implementation and it is much slower as pickle
, marshal
or even json
, but much safer for production.
The following types are supported for packing and unpacking:
None
bool
int
float
string
bytearray
(during unpacking it will be converted tobytes
)bytes
list
(during unpacking it will be converted totuple
)tuple
dict
(dict key type can be any from this list)
Installation
Requires python version 3.7 or later.
To install the latest release on PyPI, simply run:

Python library
Usage
Use like pickle
with dump
, dumps
, load
and loads
functions.
import fsPacker
data = fsPacker.dumps(["test"]*5)
print( fsPacker.loads(data) )
