dag-cbor: A Python implementation of the DAG-CBOR codec
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 the latest release from PyPI as follows:
$ pip install --upgrade dag-cborUsage
We suggest you import DAG-CBOR as follows:
>>> import dag_cbor
Below are some basic usage examples, to get you started: for detailed documentation, see https://dag-cbor.readthedocs.io/
Encoding and decoding
>>> dag_cbor.encode({'a': 12, 'b': 'hello!'})
b'\xa2aa\x0cabfhello!'
>>> dag_cbor.decode(b'\xa2aa\x0cabfhello!')
{'a': 12, 'b': 'hello!'}
Random DAG-CBOR data
>>> import pprint # pretty-printing
>>> custom_opts = dict(min_codepoint=0x41, max_codepoint=0x5a, include_cid=False)
>>> with dag_cbor.random.options(**custom_opts):
... for d in dag_cbor.random.rand_dict(3):
... pprint.pp(d)
...
