PeerState

Enum PeerState 

Source
#[repr(u8)]
pub enum PeerState { Unknown = 0, Joining = 1, Normal = 2, Standby = 3, Down = 4, Reset = 5, Leaving = 6, }
Expand description

Lifecycle state of a peer in the gossip view.

Numeric values match the reference engine’s per-node state constants (UNKNOWN, JOINING, NORMAL, STANDBY, DOWN, RESET, LEAVING).

Variants§

§

Unknown = 0

Initial state before the first observation.

§

Joining = 1

Peer is bootstrapping into the ring.

§

Normal = 2

Peer is healthy and serving traffic.

§

Standby = 3

Peer is on warm standby; requests are not routed there.

§

Down = 4

Failure detector marked the peer down.

§

Reset = 5

Peer is being re-established (connection pool reset).

§

Leaving = 6

Peer is preparing to leave the ring.

Implementations§

Source§

impl PeerState

Source

pub fn name(self) -> &'static str

Stable string label.

§Examples
use dynomite::cluster::peer::PeerState;
assert_eq!(PeerState::Normal.name(), "NORMAL");
Source

pub fn is_routable(self) -> bool

True when the dispatcher should consider this peer for routing decisions. Joining peers are accepted because the reference engine includes them in the continuum until they transition to Down or Leaving.

§Examples
use dynomite::cluster::peer::PeerState;
assert!(PeerState::Normal.is_routable());
assert!(!PeerState::Down.is_routable());
