Enum ServerState 

pub enum ServerState {
    Learner,
    Follower,
    Candidate,
    Leader,
    Shutdown,
}

All possible states of a Raft node.

Variants

Learner

The node is completely passive; replicating entries, but neither voting nor timing out.

Follower

The node is replicating logs from the leader.

Candidate

The node is campaigning to become the cluster leader.

Leader

The node is the Raft cluster leader.

Shutdown

The Raft node is shutting down.

Implementations

impl ServerState

pub fn is_learner(&self) -> bool

Check if currently in learner state.

pub fn is_follower(&self) -> bool

Check if currently in follower state.

pub fn is_candidate(&self) -> bool

Check if currently in candidate state.

pub fn is_leader(&self) -> bool

Check if currently in leader state.

Trait Implementations

impl Clone for ServerState

fn clone(&self) -> ServerState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ServerState

impl Debug for ServerState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ServerState

fn default() -> ServerState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ServerState

fn deserialize<__D>( __deserializer: __D, ) -> Result<ServerState, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ServerState

impl PartialEq for ServerState

fn eq(&self, other: &ServerState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ServerState

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
