Struct SmData 

Source 
pub struct SmData<C: RaftTypeConfig<NodeId = NodeId>, S> {
    pub last_applied_log: Option<LogId<NodeId>>,
    pub last_membership: StoredMembership<NodeId, C::Node>,
    pub state: S,
    pub current_snapshot: Option<StoredSnapshot<C>>,
}
Expand description

Internal state-machine data protected by a RwLock.

The generic parameter S is the application’s state type. It must be Default + Clone + serde::Serialize + serde::de::DeserializeOwned.

Fields§

§last_applied_log: Option<LogId<NodeId>>

Last applied log id.

§last_membership: StoredMembership<NodeId, C::Node>

Last membership config.

§state: S

Application-specific state.

§current_snapshot: Option<StoredSnapshot<C>>

Current snapshot bytes (serialized S), if any.
