type t = {
  1. dict_end_poff : Optint.Int63.t;
  2. appendable_chunk_poff : Optint.Int63.t;

  5. chunk_start_idx : int;
  6. chunk_num : int;
  7. volume_num : int;

}

The same as V4.t, with the following modifications:

New fields

  • volume_num stores the number of volumes in the lower layer.
  • mapping_end_poff stores the mapping file size (optional if missing or unknown after a migration from V4).

Changed fields

  • Replaced upgraded_from_v3_to_v4 with generic field upgraded_from to track version upgrades. Note, it is an int option since Version.t option has a bug somewhere in repr that needs further investigation.
