Member Enumeration Documentation

◆ DetailLevel

enum 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.
