The MoaT-Codec library

% start synopsis % start main

This library packages various codecs used for MoaT protocols in a way that's reason- and stream-able.

% end synopsis

Supplied codecs

% end main

encode(obj)

Encode the object to a bytestream.
decode(bytes)

Decode the given bytes to a single object.
feed(bytes, final=False)

Data stream. Returns an array of objects.

This method only exists when a sequence of encoded objects can be streamed, i.e. contains built-in message boundaries.

if @final is True, raise an exception if there is an incomplete object in the buffer after this call.
getstate(), setstate(*args)

A streaming decoder may store partially-decoded state (unprocessed buffer) here.

The list of accepted objects is implementation dependent.

Extension types vary by whether they carry binary data as in (msgpack), or objects (as in cbor).

binary (classvar): True if msgpack-style, False if cbor-style
encoder(cls, key, fn)

Encode an object obj of type type. fn(codec, obj) must return a bytestring / an encodeable object. If the registration key is None the function must return a tuple with the key as first element.
decoder(key, fn)

Add a decoder (key, data) to an object. fn(codec, data) is called with a bytestring / a decoded object, and returns whatever has been encoded.

Extensions get the codec as their first argument. They can use it to store data, e.g. references. The extension object is available as codec.ext.
