Detailed Description

Run-time heap statistics.

The value searches / allocs gives the mean number of searches per allocation, while max_search gives maximum number of searches ever performed on a single allocation call.

Lifetime number of bytes allocated from this heap.

This value is an integral multiple of the page size.

◆ lifetime_freed

uint64_t Heap_Statistics::lifetime_freed

Lifetime number of bytes freed to this heap.

This value is an integral multiple of the page size.

◆ min_free_size

uintptr_t Heap_Statistics::min_free_size

Minimum free size ever in bytes.

This value is an integral multiple of the page size.

◆ size

uintptr_t Heap_Statistics::size
