(** 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. *)

promoted_words : Core_kernel__.Import.float;

(** 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. *)

major_words : Core_kernel__.Import.float;

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

minor_collections : Core_kernel__.Import.int;

(** Number of minor collections since the program was started. *)

major_collections : Core_kernel__.Import.int;

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

heap_words : Core_kernel__.Import.int;

(** Total size of the major heap, in words. *)

heap_chunks : Core_kernel__.Import.int;

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

live_words : Core_kernel__.Import.int;

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

live_blocks : Core_kernel__.Import.int;

(** Number of live blocks in the major heap. *)

free_words : Core_kernel__.Import.int;

(** Number of words in the free list. *)

free_blocks : Core_kernel__.Import.int;

(** Number of blocks in the free list. *)

largest_free : Core_kernel__.Import.int;

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

fragments : Core_kernel__.Import.int;

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

compactions : Core_kernel__.Import.int;

(** Number of heap compactions since the program was started. *)

top_heap_words : Core_kernel__.Import.int;

(** Maximum size reached by the major heap, in words. *)

-1 means "less than", 0 means "equal", 1 means "greater than", and other values should not be returned

val min : t ‑> t ‑> t
val max : t ‑> t ‑> t
val ascending : t ‑> t ‑> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t ‑> t ‑> int
val between : t ‑> low:t ‑> high:t ‑> bool
val clamp_exn : t ‑> min:t ‑> max:t ‑> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).
