Struct BytesReadable

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

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 asyncio::*;
use asyncio::ip::*;
use asyncio::socket_base::BytesReadable;

let ctx = &IoContext::new().unwrap();
let soc = UdpSocket::new(ctx, Udp::v4()).unwrap();

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