Ppx_protocol_conv generates code to serialize and de-serialize types. The ppx itself does not contain any protocol specific code, but relies on 'drivers' that defines serialisation and de-serialisation of basic types and structures.

Pre-defined drivers are available in separate packages: ppx_protocol_conv_json (Yojson.Safe.json) ppx_protocol_conv_jsonm (Ezjson.value) ppx_protocol_conv_msgpack (Msgpck.t) ppx_protocol_conv_xml-light (Xml.xml) ppx_protocol_conv_xmlm (Xmlm.node) ppx_protocol_conv_yaml (Yaml.value)
