Codec Versioning

A python module to manage alternative versions of general-purpose binary codecs.

This python library makes it easy to manage multiple alternative versions of codecs (encoding and decoding functions). This is primarily intended for situations where codecs may be updated in the future and old codecs need to remain supported.

Use Cases

• encoded format is binary (bytes/bytearray)
• old codecs need to remain supported as new codecs are developed

Features

• manage multiple versions of codecs (encoding and decoding functions)
• define codec functions either in classes or modules as you prefer
• each codec is identified by an integer version
• when encoding, used codec's version is automatically encoded
• when decoding, the correct codec version is automatically determined
• built-in type-checking of encoded/decoded objects

Quickstart

pip install codec_versioning

See the example at ./examples/example1/example_encoding.py, and its test at ./tests/test_example.py.

Documentation

See the example at ./examples/example1/example_encoding.py, and its test at ./tests/test_example.py.

Also, this library's source code essentially comprises one small file, which should be fairly easy to undrstand: ./src/codec_versioning/codec_versioning.py
