Flynn - Simple CBOR En/Decoder

Flynn is also a Python library providing CBOR [RFC7049] encoding and decoding with a traditional buffered and a streaming interface.

Usage

The Flynn API is really simple and inspired by existing Python serialisation modules like json and pickle. The flynn module has four methods called dumps, dump, loads and load, where dumps will return the serialised input as bytes string, while dump will write the serialised input to a file descriptor. The same applies to loads and load.

>>> flynn.dumps([1, [2, 3]])
b'\x82\x01\x82\x02\x03'
>>> flynn.loads(b'\x82\x01\x82\x02\x03')
[1, [2, 3]]

Furthermore, Flynn supports generators and other iterables as input for streaming support:

>>> flynn.dumps(range(5))
b'\x9f\x00\x01\x02\x03\x04\xff'
>>> flynn.loads(b'\x9f\x00\x01\x02\x03\x04\xff')
[0, 1, 2, 3, 4]

Or to generate a map using an iterable:

>>> flynn.dumps((((a, a) for a in range(5)), "map"))
b'\xbf\x00\x00\x01\x01\x02\x02\x03\x03\x04\x04\xff'
>>> flynn.loads(b'\xbf\x00\x00\x01\x01\x02\x02\x03\x03\x04\x04\xff')
{0: 0, 1: 1, 2: 2, 3: 3, 4: 4}
