Struct ClusterState 

pub struct ClusterState {
    pub topology: Arc<RwLock<ClusterTopology>>,
    pub routing: Arc<RwLock<RoutingTable>>,
    pub multi_raft: Arc<Mutex<MultiRaft>>,
}

Result of cluster startup — everything needed to run the Raft loop.

All mutable fields are wrapped in Arc<RwLock<T>> or Arc<Mutex<T>> so subsystems started during start_cluster can hold live references to the same shared state without copying it out of the initial bootstrap result. The RunningCluster produced by the subsystem registry holds Arc clones that keep the data alive alongside the caller’s ClusterHandle.

Fields

topology: Arc<RwLock<ClusterTopology>>

routing: Arc<RwLock<RoutingTable>>

multi_raft: Arc<Mutex<MultiRaft>>
