Struct HardState 

pub struct HardState {
    pub current_term: u64,
    pub voted_for: Option<VotedFor>,
}

Hard state (Raft persistent state: term, voted_for, log)

Fields

current_term: u64

Persistent state on all servers(Updated on stable storage before responding to RPCs): latest term server has seen (initialized to 0 on first boot, increases monotonically) Terms act as a logical clock in Raft, and they allow servers to detect obsolete information such as stale leaders. Each server stores a current term number, which increases monotonically over time.

voted_for: Option<VotedFor>

Persistent state on all servers(Updated on stable storage before responding to RPCs): candidateId that received vote in current term (or null if none)
