        "description": "=========\npyringbuf\n=========\n\nA python extension implementing a circular/ring buffer of characters as a C\nextension. It overwrites silently.\n\nAvailability\n------------\n\nCurrently, pyringbuf is available at https://pypi.python.org/pypi/pyringbuf,\nor via ``pip install pyringbuf``. As this is a C extension, there is a\ncompilation step, so your system will need to be able to compile extension\nmodules for python.\n\nUsage\n-----\n\n::\n\n    >>> from ringbuf import RingBuffer\n    >>> R = RingBuffer(5)    #choose your buffer size\n    >>> R.push(\"a\")          #push a single character into the buffer\n    >>> R.pop()              #pop a single character\n    'a'\n    >>> R.write(\"bcdef\")     #fill buffer with many characters at once\n    >>> R.read(4)            #read many characters at once\n    'bcde'\n    >>> R.read(1)\n    'f'\n    >>> R.read(1)            #returns an empty string if the buffer is empty \n    ''\n\nImplementation\n--------------\n\nFor the interested, this has been implemented as a pure C extension. The ring\nbuffer itself is implemented as a fixed length array of chars (8-bit signed),\ndynamically allocated on the Python Heap on instantiation of a buffer. Read and\nwrite indexes both increase monotonically, and addresses in the array are\ndetermined using *index* % (modulo) *buffer size*. Writing more than the buffer\nsize at once throws an exception, otherwise if writing overtakes the read\nindex in the modulo space the buffer contents are silently overwritten.\n",
