Enum TrackEndpoints 

pub enum TrackEndpoints {
    Send(WebRtcTrackSink),
    Recv(WebRtcTrackSource),
    SendRecv(WebRtcTrackSink, WebRtcTrackSource),
    Inactive,
}

Available on crate feature webrtc only.

The endpoints a track actually has, which is exactly what its negotiated Direction allows — a SendOnly track carries no WebRtcTrackSource because nothing will ever arrive on it, and a RecvOnly one carries no WebRtcTrackSink because str0m has no send capability for it.

The variant is the direction, so there is no separate field the two could disagree with. Pushing into a sink that does not exist, or waiting on a source that does not, is a compile error rather than something that silently does nothing.

Fixed for the life of the track: these are handed out once, when the track attaches, and a remote peer that later renegotiates a different direction is reported on the Bus instead (see WebRtcHandle::next_track).

Variants

Send(WebRtcTrackSink)

Direction::SendOnly — outbound only.

Recv(WebRtcTrackSource)

Direction::RecvOnly — inbound only.

SendRecv(WebRtcTrackSink, WebRtcTrackSource)

Direction::SendRecv — both, on the one track.

Inactive

Direction::Inactive — neither, for now. Still handed out: the track exists and its mid is negotiated, so a caller matching attachments against its own WebRtcHandle::add_track calls has to see it.
