nb-connect

Non-blocking TCP or Unix connect.

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.

Examples

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.insert(&stream);
poller.interest(&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");
}
