Here's what you are trying to do, with a one liner:

fn get_links(mut link_nodes: Select) -> Vec<String> {
    link_nodes.retain(|node| node.value().attr("href").is_some()).into_iter().fold(Vec::new(), |links, node| links.push(link.value().attr("href").unwrap().to_string()))
}

edit: shorter and updated version:

fn get_links(mut link_nodes: Select) -> Vec<String> {
    link_nodes.into_iter().filter_map(|node| node.value().attr("href").map(|href| href.to_string())).collect()
}

The retain method is to get rid of all the nodes which don't have a href attribute and the fold method after it is to extract the href out of the nodes and push them into the vector.

It might work or not, I've written this from my memory and I can't exactly know what that Select is.

I also hope you begin reading The Book without half assing it.

All good.

lol

You also can degause the hard drives.

That assumes that the system has the gnupg utility.

That's not really my problem with GOG. It's the fact that they seem to be ignoring Linux. If they are that unwilling to make a Linux client, then I also don't want to use their platform.

Just block it and you'll no longer see any posts or comments of it.

None of the mod bots seem to be written in Rust, which I'll be using. So nope.

The bot won't have any admin permissions.

Will do.
