Hey,

Is there any way to create a macro that allows a Some<T> or T as input?

It's for creating a Span struct that I'm using:

struct Span {
    line: usize,
    column: usize,
    file_path: Option<String>,
}

...and I have the following macro:

macro_rules! span {
    ($line:expr, $column:expr) => {
        Span {
            line: $line,
            column: $column
            file_path: None,
        }
    };

    ($line:expr, $column:expr, $file_path: expr) => {
        Span {
            line: $line,
            column: $column
            file_path: Some($file_path.to_string()),
        }
    };
}

...which allows me to do this:

let foo = span!(1, 1);
let bar = span!(1, 1, "file.txt");

However, sometimes I don't want to pass in the file path directly but through a variable that is Option. To do this, I always have to match the variable:

let file_path = Some("file.txt");

let foo = match file_path {
    Some(file_path) => span!(1, 1, file_path),
    None => span!(1, 1),
}

Is there a way which allows me to directly use span!(1, 1, file_path) where file_path could be "file.txt", Some("file.txt") or None?

Thanks in advance!

Hey, Do you know any free kiosk apps (an app that only allow you to use one app) like Fully Single Kiosk App?

I recently set up Sonarr and Radarr on my home server and I'm loving it.

However, I don't get why you would ever use Lidarr. Why would you ever download music using torrents? You can use tools like spotdl and yt-dlp to download songs from YouTube music and Spotify, it's faster and more reliable; I have had some issues finding torrents of music from less-known artists.

To me it seems like it would be much better to have a tool like Lidarr or have support in Jellyseerr to download music from common streaming services.

What are your views on this?
