Hey all, i just started learning rust and completed the basics of it. and also built some beginner friendly project in it with help of chatgpt and ai. Now i am building another project for learning and get hands dirty in rust.
Just look into below code.
// it is used to listen incoming TCP connections asynchronously.
// it is non-blocking and works with async/await
use tokio::net::TcpListener;
// together these allow you to read from async stream line by line efficiently
// BufReader :- Wraps a reader and provide buffering
// Helps reduce the number of .await I/O calls by buffering the input
//
// AsyncBufReadExt :- A trait that adds methods like read_lines() and lines()
use tokio::io::{AsyncBufReadExt, BufReader};
use std::error::Error;
#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
// Bind to connection on port 6379
println!("Redis-lite server starting...");
let listener = TcpListener::bind("127.0.0.1:6379").await?;
println!("Redis-lite server listening on 6379...");
loop {
// Accept a new client connection
let (socket, addr) = listener.accept().await?;
println!("new client connected: {}", addr);
// just spawn a task as of now.
tokio::spawn(async move {
let reader = BufReader::new(socket);
let mut lines = reader.lines();
while let Ok(Some(line)) = lines.next_line().await {
println!("Received from {}: {}", addr, line);
}
println!("Client {} disconnected", addr);
});
}
}
can anyone help me and explain me what each things gonna work with appropriate example. I want deep explanation and understanding of the things in rust.
