Enum LockState 

pub enum LockState {
    Unlocked,
    Locked,
    Lost,
}

The lock-state machine. A behaviour locks onto a target (an operator designate, or an auto-lock). While Locked it is acquiring until the stream first becomes usable; once it has had a usable reading, the stream going stale or the link dropping drops it to Lost. The only way out of Lost is an explicit re-lock, there is no auto-re-acquire. A lock that has never yet had a usable reading does NOT drop to Lost (there is nothing to lose); it stays Locked, holding, until a result arrives or it is released.

Variants

Unlocked

No lock (idle).

Locked

Locked: either acquiring (no usable reading yet) or tracking.

Lost

The lock was dropped (a stream that HAD been usable went stale / the link dropped). Stays here until an explicit re-lock; never auto-re-acquires.
