✨ pylzf ✨

The python binding for liblzf

安装

pip install pylzf

使用

import pylzf

pylzf.compress(b"123", 100)
pylzf.decompress(b"xxx", 100)
data = bytearray(1000)
pylzf.compress_into(b"1212", data)
pylzf.decompress_into(b"xxxx", data)

公开函数

def compress(data: bytes, outlen: int = ...) -> bytes: ...
def decompress(data: bytes, outlen: int) -> bytes: ...
def compress_into(data: bytes, out: bytearray) -> int: ...
def decompress_into(data: bytes, out: bytearray) -> int: ...

本机编译

python -m pip install setuptools wheel cython cffi
git clone https://github.com/synodriver/pylzf
cd pylzf
git submodule update --init --recursive
python setup.py bdist_wheel --use-cython --use-cffi

后端选择

默认由py实现决定，在cpython上自动选择cython后端，在pypy上自动选择cffi后端，使用LZF_USE_CFFI环境变量可以强制选择cffi
