Rust扩展为信号协议提供Python绑定
signal-protocol的Python项目详细描述
信号协议
实验性的Python绑定到^{signal_protocolPython模块的Rust扩展。请参见here，了解在Python分配的内存中存储机密的基本限制。⚠️使用风险自负！⚠️ 在

^{pr2}$开发人员入门
您需要在系统上同时安装Rust和python3.7+。要在virtualenv中安装项目，请执行以下操作：
pip install -r requirements.txt
python setup.py develop # This will call out to rustc
然后通过pytest -v tests/运行测试，以确认所有测试都正常。测试从上游的板条箱移植到Python上。您可以将测试用作如何使用库的参考。在
