更快的python pickle替换
larch-pickle的Python项目详细描述
此模块可作为pickle的透明替换。
与原始python pickle的区别：
- no memo attribute.
- no clear_memo().
- no persistent_id interface.
- byte strings are always assumed to be utf-8 encoded.
- Pickler has an additional with_refs parameter. Setting with_refs to false, the pickler will ignore object references. This can result in an extra speed boost.
安装
落叶松泡菜需要boost库进行编译。如果boost不在 标准包含路径安装时使用：
python build_ext -I /path/to/boost install
