Struct InboundTrackStatus 

struct InboundTrackStatus {
    message: TrackStatus,
    state: TrackStatusStateMachine,
}

A track status the peer asked for with TRACK_STATUS.

Section 8.20 treats the request as a SUBSCRIBE “except it does not create downstream subscription state”, so it is recorded here and not among the subscriptions the peer has opened. Nothing that names a subscription can find it, which is the whole of what that exception asks for.

Fields

message: TrackStatus

The message as it arrived, which is what the answer is built from.

state: TrackStatusStateMachine

How far the request it opened has got.
