Encoding
The core encoding functionality is performed by the encode
function, which encods a value into a bytes
object:
>>> import dag_cbor
>>> dag_cbor.encode({'a': 12, 'b': 'hello!'})
b'\xa2aa\x0cabfhello!'
A buffered binary stream (i.e. an instance of BufferedIOBase
) can be passed to the encode
function using the optional keyword argument stream
, in which case the encoded bytes are written to the stream and the number of bytes written is returned:
>>> from io import BytesIO
>>> stream = BytesIO()
>>> dag_cbor.encode({'a': 12, 'b': 'hello!'}, stream=stream)
13
>>> stream.getvalue()
b'\xa2aa\x0cabfhello!'
