Module raft_loop 

Raft event loop — drives MultiRaft ticks and dispatches messages over the transport.

Split across files:

• loop_core: RaftLoop struct, constructors, builders, public API (propose, propose_conf_change, group_statuses), and the main run shutdown-driven loop.
• tick: one iteration of the tick pipeline — drive MultiRaft, dispatch outbound AE/RV, apply committed entries, promote caught-up learners.
• handle_rpc: inbound RPC routing (impl RaftRpcHandler). The JoinRequest arm delegates to join.
• join: async server-side JoinRequest orchestration — register peer, propose AddLearner on every group, wait for commit, broadcast topology, persist catalog, build the wire response.

Modules

handle_rpc

Inbound Raft RPC dispatch — impl RaftRpcHandler for RaftLoop.

join

Server-side JoinRequest orchestration.

loop_core

RaftLoop struct, constructors, top-level run loop, and thin wrappers over MultiRaft proposal APIs. The tick body lives in super::tick; the inbound-RPC handler lives in super::handle_rpc; the async join orchestration lives in super::join.

proposals

Raft proposal API — local and leader-forwarded proposals for both the metadata group (group 0) and data groups.

tick

Single tick of the Raft event loop.
