A thread-per-core Rust runtime with IOCP/io_uring. The name comes from "completion-based IO". This crate is inspired by monoio.
Tokio is a great generic-propose async runtime. However, it is poll-based, and even uses undocumented APIs on Windows. We would like some new high-level APIs to perform IOCP/io_uring.
Unlike tokio-uring, this runtime isn't Tokio-based.
This is mainly because that no public APIs to control IOCP in mio,
and tokio won't public APIs to control mio before mio reaches 1.0.
let buffer = compio::task::block_on(async {
let file = compio::fs::OpenOptions::new().read(true).open("Cargo.toml").unwrap();
let (read, buffer) = file.read_at(Vec::with_capacity(1024), 0).await;
let read = read.unwrap();
assert_eq!(read, buffer.len());
String::from_utf8(buffer).unwrap()
});
println!("{}", buffer);
