OwnerLiveness

Enum OwnerLiveness 

Source 
pub enum OwnerLiveness {
    ConfirmedUp,
    ConfirmedDown,
    Unconfirmed,
}
Expand description

What a TransitionTracker-style hysteresis says about one machine, crossed into this crate as plain data.

The yubaba-side original is yubaba::lease_detector::TransitionTracker::committed, which answers Option<Confirmed>. It is re-spelled rather than imported because this crate sits below both consumers and must not depend on either. The crossing is by value.

Variants§

§

ConfirmedUp

The hysteresis has committed this machine as up.

§

ConfirmedDown

The hysteresis has committed this machine as down — the only value that is positive evidence against a machine.

§

Unconfirmed

Never dwelled long enough in either direction to be committed: a freshly-elected leader’s tracker, a node mid-flap, or no detector at all. Not the same as down.
