Project description

dag-cbor: A Python implementation of DAG-CBOR

Generic badge PyPI version shields.io PyPI status Checked with Mypy Python package standard-readme compliant

This is a fully compliant Python implementation of the DAG-CBOR codec, a subset of the Concise Binary Object Representation (CBOR) supporting the IPLD Data Model and enforcing a unique (strict) encoded representation of items.

Install

You can install this package with pip:

pip install dag-cbor

Usage

The core functionality of the library is performed by the encode and decode functions:

>>> import dag_cbor
>>> dag_cbor.encode({'a': 12, 'b': 'hello!'})
b'\xa2aa\x0cabfhello!'
>>> dag_cbor.decode(b'\xa2aa\x0cabfhello!')
{'a': 12, 'b': 'hello!'}

The random module contains functions to generate random data compatible with DAG-CBOR encoding:

>>> import pprint
>>> import dag_cbor
>>> options = dict(min_codepoint=0x41, max_codepoint=0x5a, include_cid=False)
>>> with dag_cbor.random.rand_options(**options):
...     for d in dag_cbor.random.rand_dict(3):
...             pprint.pp(d)
...
