So, two struct types with the same instance-level stored properties, but one with no protocol conformance and the other with at least one, have the same stride-of? Does that mean that the latter type keeps no per-instance space for protocol support? Or that all struct types keep protocol accounting information, even when a struct’s protocol list is empty (like the former type)? >> On Feb 15, 2017, at 9:51 AM, Daryle Walker via swift-evolution >> <[email protected]> wrote: >> >> I don't know how protocol support works.
