? Less copying and/or using a single system call for a buffer.
If I have a set of blocks I want to write, I would either have to copy them into a big one just to pass them over to your API, or I would have to call your write API multiple times, which could then result in multiple write() calls.
I guess you could just use DispatchData. I’m not sure whether this is too expensive for some reason (because you may need to have to construct them, etc), or just fine.
P.S.: The DispatchData.Deallocator enum has no .nofree option. Can someone please fix that? Thanks. :-)
