A minimal, single-threaded async i/o runtime for Rust.
Only has four dependencies (libc for the poll system call, futures-util and futures-io
for the read/write traits, and socket2 for sockets). Can run Send and non-Send futures.
- tested on linux, macos and freebsd
- executor:
block_on. - task:
spawn,spawn_blocking(threadpool),JoinHandle - reactor:
AsyncRead/AsyncWrite, etc - timer:
sleep,sleep_until. - net:
TcpStream - sync:
mpsc::channel() - unsync:
mpsc::channel()(not Send + 'static but 3x faster)
There are 5 'unsafe' blocks, all in src/syscall.rs, implementing the poll(2), pipe(2) and write(2) system calls.
There's an example in examples/naratest.rs:
cargo run --example naratest
