The default CodecOptions for RawBSONDocument.

Create a new RawBSONDocument

RawBSONDocument is a representation of a BSON document that provides access to the underlying raw BSON bytes. Only when a field is accessed or modified within the document does RawBSONDocument decode its bytes.

RawBSONDocument implements the Mapping abstract base class from the standard library so it can be used like a read-only dict:

>>> from bson import encode
>>> raw_doc = RawBSONDocument(encode({'_id': 'my_doc'}))
>>> raw_doc.raw
>>> raw_doc['_id']

Changed in version 3.8: RawBSONDocument now validates that the bson_bytes passed in represent a single bson document.

Changed in version 3.5: If a CodecOptions is passed in, its document_class must be RawBSONDocument.
