run examples code in my lib error

my rust env

• windows 10
• cargo -V

  cargo 1.62.1 (a748cf5a3 2022-06-08)

I have a rust library which create by cargo new circ --bin I try to copy irc/examples/simple_plaintext.rs source code to circ/src/main.rs

when I try to build it with cargo build, cargo give three errors

Compiling circ v0.1.0 (F:\code\rust\virc\circ)

Some errors have detailed explanations: E0433, E0560, E0752.

error: could not compile `circ` due to 3 previous errors

This is src/main.rs

extern crate futures;
extern crate irc;

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

#[tokio::main]
async fn main() -> irc::error::Result<()> {
    let config = Config {
        nickname: Some("pickles".to_owned()),
        server: Some("chat.freenode.net".to_owned()),
        channels: vec!["#rust-spam".to_owned()],
        use_tls: Some(false),
        ..Default::default()
    };

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

    let mut stream = client.stream()?;
    let sender = client.sender();

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

        match message.command {
            Command::PRIVMSG(ref target, ref msg) => {
                if msg.contains(client.current_nickname()) {
                    sender.send_privmsg(target, "Hi!")?;
                }
            }
            _ => (),
        }
    }

    Ok(())
}

I just can only build examples code in git clone https://github.com/aatxe/irc.git directory

It looks like the #[tokio::main] macro is locked behind a feature now, so you'd need to add rt and macros to the feature list for the tokio crate.

thanks for you response, now I can compile fine, but a panic is triggered in the tokio library, I will continue to investigate how this error is generated

Sorry, I'm new to Rust, how do I do this?

@GTP95:

tokio = { version = "1.28.0", features = ["rt", "macros"] }
