HeapStatistics
contains memory consumption and utilization statistics for a cppgc heap.
Definition at line 19 of file heap-statistics.h.
enum cppgc::HeapStatistics::DetailLevel : uint8_t |
Specifies the detail level of the heap statistics. Brief statistics contain only the top-level allocated and used memory statistics for the entire heap. Detailed statistics also contain a break down per space and page, as well as freelist statistics and object type histograms. Note that used memory reported by brief statistics and detailed statistics might differ slightly.
