Struct PacemakerState

struct PacemakerState {
    timeouts: BTreeMap<ViewNumber, Instant>,
    timeout_vote_collectors: ActiveCollectorPair<TimeoutVoteCollector>,
    last_advance_view: Option<ViewNumber>,
}

In-memory state of a Pacemaker.

Fields

timeouts: BTreeMap<ViewNumber, Instant>

Mapping between current and future view numbers and the timeout assigned to each.

timeout_vote_collectors: ActiveCollectorPair<TimeoutVoteCollector>

TimeoutVoteCollectors for the at-most two validator sets that are active in the current view.

last_advance_view: Option<ViewNumber>

The view in which this replica last broadcasted an AdvanceView message.

Implementations

impl PacemakerState

fn initialize( config: &PacemakerConfiguration, init_view: ViewNumber, validator_set_state: &ValidatorSetState, ) -> Self

Initializes a PacemakerState upon starting the Pacemaker subprotocol.

fn update_timeouts( &mut self, epoch_start_view: ViewNumber, config: &PacemakerConfiguration, )

Update the PacemakerState’s timeouts upon entering the epoch with the given epoch_start_view.

fn extend_epoch_change_view_timeout( &mut self, epoch_change_view: ViewNumber, config: &PacemakerConfiguration, )

Extend the timeout of the epoch_change_view by another config.max_view_time.

Preconditions

The caller must ensure that epoch_change_view is actually an epoch-change view.
