Module cluster 

Cluster layer: pools, peers, datacenters, racks, gossip, snitch, vnode dispatch, and the cluster-aware Dispatcher implementation.

This module owns the cluster-wide data structures (the server pool plus the peer/dc/rack arrays). It is the seam between the per-connection state machines from crate::net (which only know about a single peer) and the routing logic that decides which peers receive a given request.

Public surface:

• peer::Peer / peer::PeerState - per-peer record.
• datacenter::Datacenter / datacenter::Rack - topology.
• vnode::dispatch - token ring lookup.
• snitch - rack-distance helpers.
• pool::ServerPool - cluster-wide owner.
• gossip::GossipState / gossip::GossipConfig - gossip bookkeeping.
• dispatch::ClusterDispatcher - the crate::net::Dispatcher implementation that replaces crate::net::NoopDispatcher for production wiring.

Examples

use dynomite::cluster::peer::{Peer, PeerEndpoint};
use dynomite::hashkit::DynToken;
let p = Peer::new(
    0,
    PeerEndpoint::tcp("127.0.0.1".into(), 8101),
    "rack1".into(),
    "dc1".into(),
    vec![DynToken::from_u32(1)],
    true,
    true,
    false,
);
assert_eq!(p.dc(), "dc1");
