Hello,

some time ago I shared a Guess game that I made from scratch and this time I thought to do something different so I decided to make a Guess game over IRC.

It’s pretty basic but I learned a lot about destructing Enum, unwrap and if let syntax.

I would appreciate any suggestion :)

here is the source code:

use futures::prelude::*;
use irc::client::prelude::*;

use rand::Rng;

#[tokio::main]
async fn main() -> irc::error::Result<()> {
    let config = Config {
        nickname: Some("beep_boop".to_owned()),
        server: Some("irc.libera.chat".to_owned()),
        channels: vec!["#test".to_owned()],
        ..Default::default()
    };

    let mut client = Client::from_config(config).await?;
    client.identify()?;

    let mut stream = client.stream()?;
    let mut secret_number = rand::thread_rng().gen_range(0..101);
    let mut attempts = 0;

    while let Some(message) = stream.next().await.transpose()? {
        print!("{}", message);

        match message.command {
            Command::PRIVMSG(channel, message) => {
                if let Some(command) = message.get(0..6) {
                    if command == "!guess" {
                        let parts = message.split(' ').collect::<Vec<_>>();
                        if let Some(part2) = parts.get(1) {
                            if let Ok(num) = part2.to_string().parse::<u32>() {
                                println!("{:?}", num);
                                if num == secret_number {
                                    client.send_privmsg(&channel, format!("You won with {attempts} attempts! generating next number")).unwrap();
                                    secret_number = rand::thread_rng().gen_range(0..101);
                                    attempts = 0; // reseting the number of attempts 
                                } else if num > secret_number {
                                    client.send_privmsg(&channel, "too high").unwrap();
                                    attempts += 1;
                                } else {
                                    client.send_privmsg(&channel, "too low").unwrap();
                                    attempts += 1;
                                }
                            }
                        }
                    }
                }
                else {
                    continue;
                }
                if message.contains(client.current_nickname()) {
                    client.send_privmsg(channel, "beep boop").unwrap();
                }
            },
            _ => println!("IRC command not implemented: {message}"),
        }
    }

    Ok(())
