Abstract concept Chunk

All chunks in a KIP Document derive from base class Chunk.

This abstract concept defines a number of methods:

• to_cbor() to produce Canonical CBOR to represent the Chunk in a KIP Document. The same call is used for saving to file, but also for streaming, and so on.

• from_cbor_array() is a class method that functions as a factory for Chunk subclasses, taking the chunk's CBOR array contents, starting with the tag of the chunk to be created. This raises an exception on syntax errors.

• from_cbor() is a class method that functions as a factory for Chunk subclasses, taking the chunk's CBOR byte representation, starting with the tag of the chunk to be created. This raises an exception on syntax errors.
