Struct asio::socket_base::BytesReadable

pub struct BytesReadable(_);

IO control command to get the amount of data that can be read without blocking.

Implements the FIONREAD IO control command.

Examples

Gettable the IO control:

use asio::*;
use asio::ip::*;
use asio::socket_base::BytesReadable;

let io = &IoService::new();
let soc = UdpSocket::new(io, Udp::v4()).unwrap();

let mut bytes = BytesReadable::default();
soc.io_control(&mut bytes).unwrap();
let sized = bytes.get();
