Should UdpSocket::bind() be async?

[Incisakura]

The only reason that these two functions are async is to resolve the addr as a domain name.
But is there anyone who binds a socket with the domain name?

Should it be better to make these functions to be non-async functions?

And should we add more #[inline] tags here?

	pub async fn bind<A: ToSocketAddrs>(addr: A) -> io::Result<UdpSocket> {
	let addrs = to_socket_addrs(addr).await?;
	let mut last_err = None;
	for addr in addrs {
	match UdpSocket::bind_addr(addr) {
	Ok(socket) => return Ok(socket),
	Err(e) => last_err = Some(e),
	}
	}
	Err(last_err.unwrap_or_else(|| {
	io::Error::new(
	io::ErrorKind::InvalidInput,
	"could not resolve to any address",
	)
	}))
	}

We could argue about this, but there's not much point. It can't be changed now regardless.

Thanks for your answer. I wish this would be "fix" oneday.
