fpath

Python的os.path模块用Rust编写

需求

• Python3
• setuptools-rust
• Nightly Rust

$ pip install setuptools_rust
$ rustup default nightly

安装

$ pip install --upgrade git+https://github.com/hhatto/fpath

使用

>>> import os.path
>>> import fpath
>>> os.path.abspath("path/to/file")
'/home/user/path/to/file'
>>> fpath.abspath("path/to/file")
'/home/user/path/to/file'
>>> import timeit
>>> timeit.timeit('import os.path;os.path.abspath("path/to/file")', number=1000*10)
0.20972810598323122
>>> timeit.timeit('import fpath;fpath.abspath("path/to/file")', number=1000*10)
0.12387347500771284
>>>
