Implementations

impl ClusterNode

pub fn new( node_id: impl Into<String>, address: impl Into<String>, role: NodeRole, health: NodeHealth, last_heartbeat_epoch: u64, ) -> Self

pub fn can_vote(&self) -> bool

Returns true if this node can participate in voting.

pub fn is_active(&self) -> bool

Returns true if this node is healthy and active.
