Struct RecvLowWatermark

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

Socket option for the receive low watermark.

Implements the SOL_SOCKET/SO_RCVLOWAT socket option.

Examples

Setting the option:

use asyncio::*;
use asyncio::ip::*;
use asyncio::socket_base::RecvLowWatermark;

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

soc.set_option(RecvLowWatermark::new(1024)).unwrap();

Getting the option:

use asyncio::*;
use asyncio::ip::*;
use asyncio::socket_base::RecvLowWatermark;

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

let opt: RecvLowWatermark = soc.get_option().unwrap();
let size: usize = opt.get();
