Pre-registering of buffers.

[andrii0lomakin]

Hi guys.
Do you have any means on the library level to pre-register buffers that are used to read/write data from/to io_uring?

Yes, We have some ideas about the IO API. Which provides methods to manipulate the buffer directly. e.g.

trait BufRead {
	async fn next(&mut self, n: usize) ->  &[u8];
	async fn peek(&mut self, n: usize) -> &[u8];
	async fn advance(&mut self, n: usize);
}

We just expose the buffer operations and we can use pre-register buffers as one of our implements.

Thank you. What about mutable form? Will it be possible not only to read but write in such a buffer?

[dyxushuai]

My mistake. This example is not the actual trait. We are still discussing this. Both BufRead and BufWrite all are required.
