a.start().await?;
Ok(())

use udp_server::UdpServer; use std::cell::RefCell; use std::error::Error;

[tokio::main]

async fn main()->Result<(),Box> { let mut a = UdpServer::new("0.0.0.0:5555").await?; a.setinput(async move |,peer,data|{ let mut token = peer.token.lock().await; match token.0 { Some(ref mut x)=>{ *x+=1; }, None=>{ token.0=Some(1); } } peer.send(&data).await?; Ok(()) });

a.start().await?;
Ok(())
