Enum ClusterLifecycleState 

pub enum ClusterLifecycleState {
    Starting,
    Restarting,
    Bootstrapping,
    Joining {
        attempt: u32,
    },
    Ready {
        nodes: usize,
    },
    Failed {
        reason: String,
    },
}

Discrete phase of this node’s cluster init.

Variants

Starting

Tracker just created, no phase decision yet.

Restarting

Catalog already marked as bootstrapped — loading from disk.

Bootstrapping

This node is the elected bootstrapper — creating a fresh cluster.

Joining

Joining an existing cluster. attempt counts from 0.

Fields

attempt: u32

Current join attempt (0-indexed). See bootstrap::config::JoinRetryPolicy for the backoff schedule.

Ready

Cluster init finished successfully. nodes is the number of members the node observed at the moment of transition.

Fields

nodes: usize

Number of peers in topology when the transition occurred.

Failed

Cluster init failed terminally. reason is a short human-readable description; see journalctl for the full context.

Fields

reason: String

One-line reason for the failure.

Implementations

impl ClusterLifecycleState

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

Short label used in the state= dimension of the nodedb_cluster_state Prometheus gauge. Stable across restarts so dashboards don’t break.

pub fn is_ready(&self) -> bool

true only in the Ready variant. Used by readiness probes.

pub fn all_labels() -> &'static [&'static str]

Every label this enum can produce. Used by the metrics endpoint to emit a one-hot gauge over the full state space.

Trait Implementations

impl Clone for ClusterLifecycleState

fn clone(&self) -> ClusterLifecycleState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClusterLifecycleState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClusterLifecycleState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ClusterLifecycleState

fn eq(&self, other: &ClusterLifecycleState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ClusterLifecycleState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
