Struct JoinLedger 

pub struct JoinLedger {
    pub arrivals: BTreeMap<String, JoinArrival>,
    pub consumed_epoch: u64,
    pub stale: Vec<StaleJoinArrival>,
    pub arrival_count: u64,
}

One join’s arrivals, kept per visit rather than per node.

The set of names that have arrived is not enough to decide a join: a visit-1 arrival and a visit-2 arrival of the same predecessor are different contributions, and a join that consumes both as one round is a join whose input never existed as a single instant of the run.

Fields

arrivals: BTreeMap<String, JoinArrival>

The latest arrival per declared predecessor.

consumed_epoch: u64

The visit epoch the join last fired at. A repeated arrival can never fire the same epoch twice.

stale: Vec<StaleJoinArrival>

Arrivals refused because a newer visit of the same predecessor had already contributed.

arrival_count: u64

How many arrivals this join has seen, across epochs.
