Stuck at this stage.
Here’s the code (Rust) :
use std::io::{BufRead, BufReader, Read, Write};
#[allow(unused_imports)]
use std::net::TcpListener;
fn main() {
let listener = TcpListener::bind("127.0.0.1:4221").unwrap();
for stream in listener.incoming() {
match stream {
Ok(mut stream) => {
let buf_reader = std::io::BufReader::new(&mut stream);
let request_line = buf_reader.lines().next().unwrap().unwrap();
let response = match request_line.as_str() {
"GET / HTTP/1.1" => "HTTP/1.1 200 OK\r\n\r\n",
_ => "HTTP/1.1 404 Not Found\r\n\r\n",
};
stream.write_all(response.as_bytes()).unwrap();
}
Err(e) => {
println!("error: {}", e);
}
}
}
}
Error:

FYI: I am not using stream.write() but i am using stream.write_all(), don’t why it’s considering stream.write() and throwing error.
