I currently have this working diesel code:

    let recent_downloads = sql::<Nullable<BigInt>>("SUM(crate_downloads.downloads)");
    let most_recently_downloaded = crates
        .left_join(
            crate_downloads::table.on(id.eq(crate_downloads::crate_id)
                .and(crate_downloads::date.gt(date(now - 90.days())))),
        )
        .group_by(id)

What is this Rust thing anyway?

Rust is a new systems programming language out of Mozilla research aiming to be a safer alternative to C and C++ without sacrificing performance. Come learn how Rust prevents buffer overflows, ensures memory safety, and prevents data races while also providing modern development workflows through Cargo and an ever-growing ecosystem of open source libraries on Crates.io. Hear about how companies like Mozilla, npm, Dropbox, and Chucklefish are using Rust to make better software. Discover how you can get involved with Rust's friendly community!
