pub fn current_usage(
store: &StateStore,
consumer_id: i64,
quotas: &ConsumerQuotas,
now_epoch_s: i64,
) -> Vec<BudgetUsage>Expand description
Read the current-window usage of every configured budget for one consumer (no reservation, no increment — the query side of metering). A store that cannot answer yields an empty read; callers surface the gap their own way (the admin endpoint 500s, the gauge refresh skips).
