Add safer abstractions for buffer rings #256

Closed SUPERCILEX closed 4 months ago

SUPERCILEX commented 9 months ago

See https://github.com/tokio-rs/tokio-uring/issues/112#issuecomment-1903356303

I'm leaving this in the draft state until I've fully built out my server and fuzzed it while using this API to battle test it.

Ok, I've been running this for a while and I'm pretty confident it works at this point. I also expanded the API to support back pressure by carrying the buffer token through several io_uring steps before releasing it back to the kernel (that way if a client spams requests, it'll run out of buffers and need to wait until the server is ready to accept more).

I'm not really happy with the API, but I do think it gets the job done. Thoughts on it? I can add docs if we're going forward with it.

Also in case anyone's interested, here's how I'm using this: https://github.com/SUPERCILEX/clipboard-history/blob/418b2612f8e62693e42057029df78f6fbf49de3e/server/src/reactor.rs#L248

Closing as I'm probably the only one using this. The canonical implementation now lives in https://github.com/SUPERCILEX/clipboard-history/blob/9662f08b43502feafceec0c694237498bc7ea127/server/src/io_uring.rs#L167
