The type for stats for a store S.

  • finds stores the total number of calls to S.find, and tracks the source locations of successful finds (i.e. whether the value was recovered from the staging table, LRU, or the pack file);
  • appended_hashes is the number of times a hash was appended, during calls to add;
  • appended_offsets is the number of times an offset was appended, during calls to add;
  • inode_add + inode_remove + inode_of_seq + inode_of_raw is the total number of Inode.Val.t built;
  • inode_rec_add + inode_rec_remove are witnesses of the quantity of work that is done modifying inodes;
  • inode_to_binv is the number of Inode.Bin.v built;
  • inode_encode_bin is the number of Bin to Compress conversions;
  • inode_decode_bin is the number of Compress to Bin conversions;
