pub fn outcome_counts(executions: &[Execution]) -> BTreeMap<String, usize>Expand description
How many of these executions there are of each outcome, keyed by the outcome’s serde
word; an outcome nothing recorded is absent rather than 0. The one count
Ledger::by_outcome and a run record’s totals both use.
