Struct TrackExistence 

pub(crate) struct TrackExistence {
    locations: Arc<Mutex<TrackLocations>>,
    namespace: TrackNamespace,
    name: Vec<u8>,
}

One track’s record of which Objects exist and which do not.

Keyed on the track rather than on an alias, because a FETCH stream names none and its objects are judged against the same record a subscription’s are.

Fields

locations: Arc<Mutex<TrackLocations>>

namespace: TrackNamespace

name: Vec<u8>
