Enum PhiTransition 

Source 
pub enum PhiTransition {
    Live {
        site: NodeSiteId,
    },
    Suspect {
        site: NodeSiteId,
        phi: f64,
    },
    Down {
        site: NodeSiteId,
        phi: f64,
    },
}
Expand description

State transitions surfaced by RttTracker::scan_phi. The engine maps each entry onto a bus crate::bus::InfraEvent::PeerSuspect / crate::bus::InfraEvent::PeerDown / crate::bus::InfraEvent::PeerLive.

Variants§

§

Live

Site recovered (φ collapsed below suspect threshold).

Fields

§site: NodeSiteId

Per-Node site whose φ-accrual detector dropped back below the suspect threshold.

§

Suspect

Site crossed the suspect threshold.

Fields

§site: NodeSiteId

Per-Node site whose φ-accrual detector crossed into the suspect band.

§phi: f64

φ value at the moment the suspect threshold was crossed.

§

Down

Site crossed the hard-down threshold.

Fields

§site: NodeSiteId

Per-Node site whose φ-accrual detector crossed into the hard-down band.

§phi: f64

φ value at the moment the hard-down threshold was crossed.
