debugAllKeys property
All currently-live keys, in nid order. Debug-only accessor for tests that need to pick a random key from the live set.
Implementation
@visibleForTesting
Iterable<TKey> get debugAllKeys sync* {
for (int nid = 0; nid < _nids.length; nid++) {
final key = _nids.keyOf(nid);
if (key != null) {
yield key;
}
}
