Struct asio::socket_base::Linger

pub struct Linger(_);

Socket option to specify whether the socket lingers on close if unsent data is present.

Implements the SOL_SOCKET/SO_LINGER socket option.

Examples

Setting the option:

use asio::*;
use asio::ip::*;
use asio::socket_base::Linger;

let io = &IoService::new();
let soc = TcpSocket::new(io, Tcp::v4()).unwrap();

soc.set_option(Linger::new(Some(30))).unwrap();

Getting the option:

use asio::*;
use asio::ip::*;
use asio::socket_base::Linger;

let io = &IoService::new();
let soc = TcpSocket::new(io, Tcp::v4()).unwrap();

let opt: Linger = soc.get_option().unwrap();
let is_set: Option<u32> = opt.get();
