Module datagram_prefix 

The fields of a received datagram up to its Extension Headers Length.

On drafts 11 through 16 the codec’s datagram header decoder refuses an announced extension block with a length of 0 as a bare InvalidField, which it also returns for other faults. Each draft’s recv_datagram reads the prefix again here, after that refusal, to tell whether the empty block was the fault, since the drafts answer it with a session close.
