@type partition_entry() :: %{
  :id => non_neg_integer(),
  optional(:digest) => binary() | nil,
  optional(:bval) => integer() | nil
}

Per-partition resume state used by scan/query pagination.

:digest and :bval represent the last server cursor position for the partition, not user-key order.

@type t() :: %Aerospike.PartitionFilter{
  begin: non_neg_integer(),
  count: pos_integer(),
  digest: binary() | nil,
  done?: boolean(),
  partitions: [partition_entry()],
  retry?: boolean()
}

Partition selection and resume state for scans and queries.

begin and count select the partition range for new work. digest is an optional digest resume point. partitions carries per-partition resume entries produced during pagination. done? and retry? are runtime state flags used by the scan/query executor.
