Building an Async RTSP Client in Rust with Tokio

use tokio::net::TcpStream;
use tokio::io::{AsyncWriteExt, AsyncReadExt};

#[tokio::main]
async def main() -> Result<(), Box<dyn std::error::Error>> {
    let mut stream = TcpStream::connect("rtsplink.com:554").await?;
    let req = "OPTIONS rtsp://rtsplink.com/live/test RTSP/1.0\r\nCSeq: 1\r\nUser-Agent: RTSPLinkRust/1.0\r\n\r\n";
    stream.write_all(req.as_bytes()).await?;

    let mut buf = [0u8; 1024];
    let n = stream.read(&mut buf).await?;
    println!("RTSP Response:\n{}", String::from_utf8_lossy(&buf[..n]));
    Ok(())
