Yes, but let's make clear that unsafe.SizeOf(slice) and len(slice) are independent, unrelated values. > What are other idiomatic ways to determine the runtime memory use of a struct which contains (among other things) slices? Use unsafe.SizeOf as you do, it works correctly. The items of a slice are not part of the slice variable/field but are allocated independently elsewhere. The items are found at &slice[0] when len(slice) -- -j -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
