type t = {
  1. minor_words : Base.Float.t;
    (*

    Number of words allocated in the minor heap since the program was started. This number is accurate in byte-code programs, but only an approximation in programs compiled to native code.

    *)
  2. promoted_words : Base.Float.t;
    (*

    Number of words allocated in the minor heap that survived a minor collection and were moved to the major heap since the program was started.

    *)
  3. major_words : Base.Float.t;
    (*

    Number of words allocated in the major heap, including the promoted words, since the program was started.

    *)
  4. minor_collections : Base.Int.t;
    (*

    Number of minor collections since the program was started.

    *)
  5. major_collections : Base.Int.t;
    (*

    Number of major collection cycles completed since the program was started.

    *)
  6. heap_words : Base.Int.t;
    (*

    Total size of the major heap, in words.

    *)
  7. heap_chunks : Base.Int.t;
    (*

    Number of contiguous pieces of memory that make up the major heap.

    *)
  8. live_words : Base.Int.t;
    (*

    Number of words of live data in the major heap, including the header words.

    *)
  9. live_blocks : Base.Int.t;
    (*

    Number of live blocks in the major heap.

    *)
  10. free_words : Base.Int.t;
    (*

    Number of words in the free list.

    *)
  11. free_blocks : Base.Int.t;
    (*

    Number of blocks in the free list.

    *)
  12. largest_free : Base.Int.t;
    (*

    Size (in words) of the largest block in the free list.

    *)
  13. fragments : Base.Int.t;
    (*

    Number of wasted words due to fragmentation. These are 1-words free blocks placed between two live blocks. They are not available for allocation.

    *)
  14. compactions : Base.Int.t;
    (*

    Number of heap compactions since the program was started.

    *)
  15. top_heap_words : Base.Int.t;
    (*

    Maximum size reached by the major heap, in words.

    *)
  16. stack_size : Base.Int.t;
    (*

    Current size of the stack, in words.

    *)
  17. forced_major_collections : Base.Int.t;
    (*

    Number of forced full major collection cycles completed since the program was started.

    *)

diff after before computes after-before pointwise across each field; this helps show the effect (on all stats) of some code block.
