Detailed Description

HeapStatistics contains memory consumption and utilization statistics for a cppgc heap.

Member Enumeration Documentation

◆ DetailLevel

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.

Member Data Documentation

◆ committed_size_bytes

size_t cppgc::HeapStatistics::committed_size_bytes = 0

Overall committed amount of memory for the heap.

◆ detail_level

DetailLevel cppgc::HeapStatistics::detail_level

Detail level of this HeapStatistics.

◆ resident_size_bytes

size_t cppgc::HeapStatistics::resident_size_bytes = 0

Resident amount of memory held by the heap.

◆ space_stats

std::vector<SpaceStatistics> cppgc::HeapStatistics::space_stats

Statistics for each of the spaces in the heap. Filled only when detail_level is DetailLevel::kDetailed.

◆ type_names

std::vector<std::string> cppgc::HeapStatistics::type_names

Vector of cppgc::GarbageCollected type names.

◆ used_size_bytes

size_t cppgc::HeapStatistics::used_size_bytes = 0

Amount of memory actually used on the heap.
