fn kind_of(stream_kind: DataStreamType) -> MatchKindExpand description
Which MatchKind a framed object’s stream is.
The Fetch arm is live, on all the drafts:
detect_stream_type maps stream type 0x05 to
DataStreamType::Fetch and the framer produces ordinary ObjectMeta
for it. On drafts 18-23 that needs the fetch’s Group Order, which
the session reads off the FETCH before the response opens; a response
naming a request nobody made is bypassed and says so per stream, and
produces no meta for a rule to be measured against either way.
the_fetch_arm_claims_a_fetch_object is what keeps the arm from being
deletable without a red.
