caterpillar

Caterpillar is a Python library designed for the efficient packing and unpacking of structured binary data, building upon Python's native `struct` capabilities. Its primary use case is facilitating the declaration of custom data structures through Python class definitions, enabling features like dynamic endian configuration, inheritance-based struct adaptation, and the implementation of bitfields and unions. Notable functionalities include memory optimization via `__slots__`, type compliance for static checking, and extensibility for custom parsing logic written in C or C++.
