fn rev_epoch_ranges(
start_after: ChronologicalOperationLogKey,
last_entry: ChronologicalOperationLogKey,
epoch_duration: Duration,
) -> impl Iterator<Item = Range<ChronologicalOperationLogKey>>Expand description
Returns an iterator over the ranges of operation log keys, starting from the
most recent range and going backwards in time till slightly later than
last_entry.
Simplifying keys to integers and assuming a start_after of 100, a
last_entry of 55 and an epoch_duration of 10 the ranges would be:
[90..100, 80..90, 70..80, 60..70, 50..60]
