I'm unable to start the tutorial as a systemd service at boot.

[Folaht]

Setup: RPi4 - Manjaro ARM

The error I get:

mai 25 12:27:25 Klav TestBot[225]: Error: Io(Custom { kind: Other, error: "failed to lookup address information: Temporary failure in name resolution" })
mai 25 12:27:25 Klav systemd[1]: testbot.service: Control process exited, code=exited, status=1/FAILURE
mai 25 12:27:25 Klav systemd[1]: testbot.service: Failed with result 'exit-code'.
mai 25 12:27:25 Klav systemd[1]: Failed to start Test bot..

My code:

main.rs

// main.rs

extern crate irc;

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

#[tokio::main]
async fn main() -> Result<(), failure::Error> {
    let config = Config {
      nickname: Some("Testbot".to_owned()),
      server: Some("irc.privchat.net".to_owned()),
      port: Some(6697),
      channels: vec!["#testbots".to_owned()],
      username: Some("testbot".to_owned()),
      realname: Some("Testbot".to_owned()),          
      use_tls: Some(true),
      alt_nicks: vec!["Testbot_".to_owned()],
      .. Default::default()
    };

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

    let mut stream = client.stream()?;

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

    Ok(())
}

And my systemd service.

testbot.service

[Unit]
Description=Test bot
After=network-online.target

[Service]
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin/:/bin" "TZ=CEST"

Looks like I'm using old code, closing this issue.

[update] Reopening because the new code is causing a very similar error, which I edited above.

As I understand it, the error you're encountering occurs when name resolution fails. I don't know for certain, but my impression is that you ultimately end up trying to connect before your machine has established an internet connection. You'll want to change the program to re-attempt connection in a loop, most likely.

Solved by adding:

Wants=network-online.target

I'm going to link myself to this before I keep reopening this issue:
