How to set custom fingerprints in the Sentry SDK for Rust?

I would like to set a custom fingerprint for my events using the Sentry SDK for Rust, but I could not find any examples on how to do it.

The official documentation lacks any mention of SDK fingerprinting (unlike the documentation for other platforms). I found a github issue stating that the documentation is missing this bit.

Does anyone have any examples to share?

After some digging, I found this example directly from the sentry-rust repository:

fn main() {
    let _sentry = sentry::init(sentry::ClientOptions {
        release: sentry::release_name!(),
        debug: true,
        ..Default::default()
    });
    sentry::configure_scope(|scope| {
        scope.set_fingerprint(Some(["my custom fingerprint"].as_ref()));
        scope.set_tag("foo", "bar");
    });

    sentry::capture_message("my message", sentry::Level::Warning);
}

which seems to work in my case.
