the code I have written isn’t very idiomatic or efficient. I am still new to Rust so I am learning things. I am amazed that I can write a pastebin in just 60 lines of Rust code. It’s awesome. I am thinking about deploying it on my server. any suggestions would be appreciated :) code: use axum::{extract::Path, routing::get, Router}; use std::fs::{read_to_string, File}; use std::io::prelude::*; use std::net::{TcpListener, TcpStream}; use std::str; const MAX_FILE_SIZE: usize = 1024 * 1024 * 10; static mut FILE_COUNT: usize = 0; fn handle_client(stream: &mut TcpStream) -> std::io::Result<()> { let mut buf = vec![0; 1024]; unsafe { let file_name = FILE_COUNT.to_string(); FILE_COUNT += 1; let mut file = File::create(file_name)?; let mut size: usize = 0; loop { let read_data = stream.read(&mut buf).unwrap(); size += read_data; if size >= MAX_FILE_SIZE { return Ok(()) } if read_data == 0 { return Ok(()); } stream.write_all(&buf[..read_data]).unwrap(); write!(file, "{}", str::from_utf8(&buf[..read_data]).unwrap())?; } } } async fn upload_handle() -> std::io::Result<()> { let listener = TcpListener::bind("127.0.0.1:8080")?; // accept connections and process them serially for stream in listener.incoming() { handle_client(&mut stream?)?; } Ok(()) } async fn handle(Path(id): Path) -> String { if let Ok(content) = read_to_string(id) { return content; } return String::from("ERROR: File not found"); } #[tokio::main] async fn main() { tokio::spawn(upload_handle()); let app = Router::new() .route("/", get(|| async { "Paste something in pastebin!" })) .route("/{id}", get(handle)); let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap(); axum::serve(listener, app).await.unwrap(); }
