The Node API

Node<S> is the handle to a running node. Cloning it is cheap; every clone shares the driver task.

Starting

#![allow(unused)]
fn main() {
let node = Node::start(config, state_machine, storage, transport).await?;
}

Node::start recovers persisted state, builds the engine, and spawns the driver, ticker, and apply tasks. See Configuration and Bootstrap modes.

Method	Behavior
`write(cmd)`	Preferred client-write API. Returns when the command commits and applies.
`propose(cmd)`	Compatibility alias for `write(cmd)`.
`add_peer(id)` / `remove_peer(id)`	§4.3 single-server membership change.
`read_linearizable(closure)`	Run `closure` against the state machine at a linearizable read point (ReadIndex, §8).
`admin()`	Return an operator-facing handle for membership and lifecycle operations.
`current_leader()`	Return the current leader hint, if known.
`transfer_leadership_to(peer)`	Hand leadership to a follower.
`status()`	Current role, term, commit index, known leader.
`node_metrics()`	Runtime-facing metrics wrapper around the raw engine counters and gauges.
`shutdown()`	Drain and stop every background task.

See rustdoc for Node for full signatures.
