我如何在未来的链中读到tokio :: net :: TcpStream？

Question

I would like to read data from the TcpStream until I encounter a '\\0'. The issue is that tokio::io::read_until needs the stream to be BufRead .

fn poll(&mut self) -> Poll<(), Self::Error> {
    match self.listener.poll_accept()? {
        Async::Ready((stream, _addr)) => {
            let task = tokio::io::read_until(stream, 0, vec![0u8; buffer])
                 .map_err(|_| ...)
                 .map(|_| ...);
            tokio::spawn(task);
        }
        Async::NotReady => return Ok(Async::NotReady),
    }
}

How can I read data from the TcpStream this way?

Reading the documentation for BufRead , you'll see the text:

If you have something that implements Read , you can use the BufReader type to turn it into a BufRead .

fn example(stream: TcpStream) {
    io::read_until(std::io::BufReader::new(stream), 0, vec![]);
}
