This crate allows you to create a [`TcpStream`] or a [`UnixStream`] in a non-blocking way, without waiting for the connection to become fully established. [`TcpStream`]: https://doc.rust-lang.org/stable/std/net/struct.TcpStream.html [`UnixStream`]: https://doc.rust-lang.org/stable/std/os/unix/net/struct.UnixStream.html ## Examples ```rust use polling::{Event, Poller}; use std::time::Duration; // Create a pending TCP connection. let stream = nb_connect::tcp(([127, 0, 0, 1], 80))?; // Create a poller that waits for the stream to become writable. let poller = Poller::new()?; poller.add(&stream, Event::writable(0))?; // Wait for at most 1 second. if poller.wait(&mut Vec::new(), Some(Duration::from_secs(1)))? == 0 { println!("timeout"); } else if let Some(err) = stream.take_error()? { println!("error: {}", err); } else { println!("connected"); } ``` ## License Licensed under either of * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. #### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
