Struct KeepAlive

pub struct KeepAlive(/* private fields */);

Socket option to send keep-alives.

Implements the SOL_SOKCET/SO_KEEPALIVE socket option.

Examples

Setting the option:

use asyncio::*;
use asyncio::ip::*;
use asyncio::socket_base::KeepAlive;

let ctx = &IoContext::new().unwrap();
let soc = TcpSocket::new(ctx, Tcp::v4()).unwrap();

soc.set_option(KeepAlive::new(true)).unwrap();

Getting the option:

use asyncio::*;
use asyncio::ip::*;
use asyncio::socket_base::KeepAlive;

let ctx = &IoContext::new().unwrap();
let soc = TcpSocket::new(ctx, Tcp::v4()).unwrap();

let opt: KeepAlive = soc.get_option().unwrap();
let is_set: bool = opt.get();
