zerocopy network #16

Open quininer opened 4 years ago

quininer commented 4 years ago

I had this idea long ago, and the poll-based API is not suitable for zerocopy network because it has similar problems as io-uring. It needs to make kernel hold buffer ownership.

I tried it with Sink, but it didn't finish in the end. I think it will be more applicable to io-uring.

I don't think there is any difficulty, but the crate now more forcus for file io.
