Structurally tag binary serialisation stream.

Say you have:

Say you have a data type

data Record = Record
  { _recordFields  :: HM.HashMap Text (Integer, ByteString)
  , _recordEnabled :: Bool
  }
  deriving (Eq, Show, Generic)

instance Binary Record
instance Structured Record

then you can serialise and deserialise Record values with a structure tag by simply

structuredEncode record :: LBS.ByteString
structuredDecode lbs    :: IO Record

If structure of Record changes in between, deserialisation will fail early.

The overhead is next to non-observable.
