Function wrap

pub fn wrap<T, F, R, E>(handler: F, data: &Arc<T>) -> ArcHandler<T, F, R, E>

Provides a Arc handler to asynchronous operation.

The ArcHandler has trait the Handler, that type of Handler::Output is ().

Examples

use std::io;
use std::sync::{Arc, Mutex};
use asyncio::{IoContext, wrap};
use asyncio::ip::{IpProtocol, Tcp, TcpSocket, TcpEndpoint, TcpListener};

fn on_accept(soc: Arc<Mutex<TcpListener>>, res: io::Result<(TcpSocket, TcpEndpoint)>) {
  if let Ok((acc, ep)) = res {
    println!("accepted {}", ep)
  }
}

let ctx = &IoContext::new().unwrap();
let soc = Arc::new(Mutex::new(TcpListener::new(ctx, Tcp::v4()).unwrap()));
soc.lock().unwrap().async_accept(wrap(on_accept, &soc));
