Module Gc.Stat
type t
=
{
minor_words : Core_kernel__.Import.float;
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.
stack_size : Core_kernel__.Import.int;
Current size of the stack, in words.

exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variantt
afterwards.
