Struct TrackRecord 

struct TrackRecord {
    namespace: TrackNamespace,
    name: Vec<u8>,
    reached: Option<ObjectLocation>,
    final_object: Option<ObjectLocation>,
}

One track and how far its objects have reached.

Fields

namespace: TrackNamespace

name: Vec<u8>

reached: Option<ObjectLocation>

The largest Group ID seen, and the largest Object ID seen in that group. None until the track has carried an object with status Normal.

final_object: Option<ObjectLocation>

Where the track ended, once an end-of-track object has said so and been found to be in a place the track could end at.

None on a track still running, and on one whose end-of-track object was refused — an object the draft calls a protocol error settles nothing, so nothing after it is measured against where it claimed the track stopped.
