C-based extension implementing fast integer bit sets
intbitset is on PyPI so all you need is:
pip install intbitset
Provides an intbitset data object holding unordered sets of unsigned integers with ultra fast set operations, implemented via bit vectors and Python C extension to optimize speed and memory usage.
Emulates the Python built-in set class interface with some additional specific methods such as its own fast dump and load marshalling functions. Uses real bits to optimize memory usage, so may have issues with endianness if you transport serialized bitsets between various machine architectures.
Please note that no bigger than __maxelem__ elements can be added to an intbitset.
>>> x = intbitset([1,2,3]) >>> y = intbitset([3,4,5]) >>> print x & y intbitset() >>> print x | y intbitset([1, 2, 3, 4, 5])
Complete documentation is available at <http://intbitset.readthedocs.org> or can be build using Sphinx:
pip install Sphinx python setup.py build_sphinx
Running the tests are as simple as:
python setup.py test
or (to also show test coverage)
