/*
  A "Get next" function for partition iterator.

SYNOPSIS
    partition_iter_func()
      part_iter  Partition iterator, you call only "iter.get_next(&iter)"

DESCRIPTION
    Depending on whether partitions or sub-partitions are iterated, the
    function returns next subpartition id/partition number. The sequence of
    returned numbers is not ordered and may contain duplicates.

When the end of sequence is reached, NOT_A_PARTITION_ID is returned, and 
    the iterator resets itself (so next get_next() call will start to 
    enumerate the set all over again).

RETURN 
    NOT_A_PARTITION_ID if there are no more partitions.
    [sub]partition_id  of the next partition
*/

typedef uint32 (*partition_iter_func)(st_partition_iter* part_iter);

/*
  Partition set iterator. Used to enumerate a set of [sub]partitions
  obtained in partition interval analysis (see get_partitions_in_range_iter).

For the user, the only meaningful field is get_next, which may be used as
  follows:
             part_iterator.get_next(&part_iterator);
  
  Initialization is done by any of the following calls:
    - get_partitions_in_range_iter-type function call
    - init_single_partition_iterator()
    - init_all_partitions_iterator()
  Cleanup is not needed.

  Get an iterator for set of partitions that match given field-space interval

SYNOPSIS
    get_partitions_in_range_iter()
      part_info            Partitioning info
      is_subpart
      store_length_array   Length of fields packed in opt_range_key format
      min_val              Left edge,  field value in opt_range_key format
      max_val              Right edge, field value in opt_range_key format
      min_len              Length of minimum value
      max_len              Length of maximum value
      flags                Some combination of NEAR_MIN, NEAR_MAX, NO_MIN_RANGE,
                           NO_MAX_RANGE
      part_iter            Iterator structure to be initialized

DESCRIPTION
    Functions with this signature are used to perform "Partitioning Interval
    Analysis". This analysis is applicable for any type of [sub]partitioning 
    by some function of a single fieldX. The idea is as follows:
    Given an interval "const1 <=? fieldX <=? const2", find a set of partitions
    that may contain records with value of fieldX within the given interval.

The min_val, max_val and flags parameters specify the interval.
    The set of partitions is returned by initializing an iterator in *part_iter

NOTES
    There are currently three functions of this type:
     - get_part_iter_for_interval_via_walking
     - get_part_iter_for_interval_cols_via_map
     - get_part_iter_for_interval_via_mapping

RETURN 
    0 - No matching partitions, iterator not initialized
    1 - Some partitions would match, iterator intialized for traversing them
   -1 - All partitions would match, iterator not initialized
