Struct Draft16FetchStream 

pub struct Draft16FetchStream {
    stream: FramedRecvStream,
    reader: FetchObjectReader,
}

Draft-16’s fetch stream, carried with the resolver its objects need.

The one variant of AnyFetchReader that is not a bare stream, and the reason is a gap one draft wide. All but one of the per-draft FramedRecvStreams resolve a fetch object’s elided fields themselves — drafts 07 through 14 have nothing to resolve, and 15, 17, 18, 19 and 20 each hold a FetchObjectReader on the stream. Draft-16’s does not, though moqtap_codec::draft16::data_stream::FetchObjectReader exists and does exactly the job.

So the state lives here. It has to live somewhere per stream: a draft-16 object may leave out its Group ID, its Subgroup ID, its Object ID and its Priority, and Table 5 gives each absent field a meaning drawn from the object before it. A reader without the object before it does not get a worse answer, it gets no answer at all.

Fields

stream: FramedRecvStream

reader: FetchObjectReader

Implementations

impl Draft16FetchStream

pub fn stream_id(&self) -> u64

Which stream this fetch arrived on, on the terms AnySubgroupWriter::stream_id describes.
