Function set_keepalive

pub fn set_keepalive(socket: &TcpStream, ttl: Duration) -> Result<()>

Sets the TCP keepalive behavior on a socket.

This is the equivalent of setting the SO_KEEPALIVE and TCP_KEEPALIVE socket settings directly.

Errors

If there is an error with either enabling keepalive probes or setting the TCP keepalive idle timeout on the given socket, an error variant will be returned explaining the underlying I/O error.
