Struct TcpKeepalive 

pub struct TcpKeepalive {
    pub time: Option<Duration>,
    pub interval: Option<Duration>,
    pub retries: Option<u32>,
}

When an idle connection’s keepalive probes start, how far apart they go, and how many unanswered ones drop the connection. A field left None keeps the system’s value.

Times are whole seconds, as the system takes them: a part of one counts as one more.

use std::time::Duration;
use nuclei::net::{TcpKeepalive, TcpSocket};

let socket = TcpSocket::new_v4()?;
socket.set_keepalive_timing(TcpKeepalive {
    time: Some(Duration::from_secs(60)),
    interval: Some(Duration::from_secs(10)),
    retries: Some(5),
})?;
assert!(socket.keepalive()?);

Fields

time: Option<Duration>

How long the connection is idle before the first probe.

interval: Option<Duration>

How long after an unanswered probe the next one goes.

retries: Option<u32>

How many unanswered probes drop the connection.
