Struct Persist 

pub struct Persist {
    pub term: Term,
    pub voted_for: Option<NodeId>,
    pub hard_state_dirty: bool,
    pub truncate_from: Option<LogIndex>,
    pub entries: Vec<LogEntry>,
}

A batch of durable state changes an outer runtime must fsync before acting on any network effect drained from the same step (Raft §5.1–§5.3): a follower persists appended entries before ack’ing them, and a node persists its term/vote before replying to a vote. Produced by RaftNode::take_persist; it is the delta since the previous call.

Fields

term: Term

Current term to record in the hard state.

voted_for: Option<NodeId>

Vote cast in term, to record in the hard state.

hard_state_dirty: bool

Whether the hard state (term/voted_for) actually changed and must be written; false means only the log changed this step.

truncate_from: Option<LogIndex>

When set, the persisted log suffix at indices >= from must be truncated before entries are appended (conflict resolution, Raft §5.3).

entries: Vec<LogEntry>

Entries to append after any truncation (ascending, contiguous).
