fun should be a function created with *WithReserved API above.
Such functions have 2 reserved slots, and which can be either 0 or 1. GetGCHeapSizeForZone ⚠ This function reports the amount of GC heap memory referred to from this
zone. GetGCHeapUsage ⚠ GetJITHeapSizeForZone ⚠ This function reports the amount of JIT memory used by this zone. GetMallocHeapSizeForZone ⚠ This function reports the size of all malloc memory referred to from this
zone. GetMapObjectKeysAndValuesInterleaved ⚠ GetMemoryUsageForZone ⚠ This function reports memory used by a zone in bytes, this includes: GetObjectProto ⚠ GetObjectZoneFromAnyThread ⚠ GetPropertyKeys ⚠ Add some or all property keys of obj to the id vector *props.
