Function connect_timeout

pub fn connect_timeout<A: ToSocketAddrs>(
    addr: A,
    timeout: Duration,
) -> Result<TcpStream>

Opens a TCP connection to a remote host.

addr is an address of the remote host. Anything which implements ToSocketAddrs trait can be supplied for the address; see this trait documentation for concrete examples.

If addr yields multiple addresses, connect will be attempted with each of the addresses until a connection is successful. If none of the addresses result in a successful connection, the error returned from the last connection attempt (the last address) is returned.

Examples

Open a TCP connection to 127.0.0.1:8080:

if let Ok(stream) = open_coroutine::connect_timeout("127.0.0.1:8080", std::time::Duration::from_secs(3)) {
    println!("Connected to the server!");
} else {
    println!("Couldn't connect to server...");
}

Open a TCP connection to 127.0.0.1:8080. If the connection fails, open a TCP connection to 127.0.0.1:8081:

use std::net::SocketAddr;

let addrs = [
    SocketAddr::from(([127, 0, 0, 1], 8080)),
    SocketAddr::from(([127, 0, 0, 1], 8081)),
];
if let Ok(stream) = open_coroutine::connect_timeout(&addrs[..], std::time::Duration::from_secs(3)) {
    println!("Connected to the server!");
} else {
    println!("Couldn't connect to server...");
}
