cobs 0.7.0

Consistent Overhead Byte Stuffing (COBS)

Python functions for encoding and decoding COBS.

Intro

Functions are provided for encoding and decoding according to the basic COBS method. The COBS variant “Zero Pair Elimination” (ZPE) is not implemented.

A pure Python implementation and a C extension implementation are provided. If the C extension is not available for some reason, the pure Python version will be used.
