Struct raftify::Raft

pub struct Raft<LogEntry: AbstractLogEntry + 'static, FSM: AbstractStateMachine + Clone + 'static> {
    pub raft_node: RaftNode<LogEntry, FSM>,
    pub raft_server: RaftServer<LogEntry, FSM>,
    pub tx_server: Sender<ServerRequestMsg<LogEntry, FSM>>,
    pub logger: Arc<dyn Logger>,
}

This structure contains functions required for Raft bootstrap along with RaftNode and RaftServer instances. The bootstrap function returns an instance of the Raft type that deref to RaftNode type, allowing the use of functions necessary for interaction with the cluster.

Fields

raft_node: RaftNode<LogEntry, FSM>

raft_server: RaftServer<LogEntry, FSM>

tx_server: Sender<ServerRequestMsg<LogEntry, FSM>>

logger: Arc<dyn Logger>

Implementations

impl<LogEntry: AbstractLogEntry, FSM: AbstractStateMachine + Clone + Send + Sync + 'static> Raft<LogEntry, FSM>

pub fn bootstrap<A: ToSocketAddrs>( node_id: u64, raft_addr: A, fsm: FSM, config: Config, logger: Arc<dyn Logger> ) -> Result<Self>

Creates a new Raft instance. Cloning a Raft instance does not bootstrap a new Raft instance. To bootstrap a new Raft instance, call this associated function.

pub async fn run(self) -> Result<()>

Starts the RaftNode and RaftServer.

pub async fn request_id<A: ToSocketAddrs>( raft_addr: A, peer_addr: String ) -> Result<ClusterJoinTicket>

Requests a cluster join ticket from the peer. You can use this to dynamically add members in addition to initial_peers.

Trait Implementations

impl<LogEntry: Clone + AbstractLogEntry + 'static, FSM: Clone + AbstractStateMachine + Clone + 'static> Clone for Raft<LogEntry, FSM>

fn clone(&self) -> Raft<LogEntry, FSM>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<LogEntry: AbstractLogEntry + 'static, FSM: AbstractStateMachine + Clone + 'static> Deref for Raft<LogEntry, FSM>

type Target = RaftNode<LogEntry, FSM>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
