Module scheduling 

Scheduling — the tasks and commands that need more than the scheduler crate depends on.

rainier-scheduler knows about the container and the cache and nothing else, which is what keeps it usable without a queue or a console. The two things people actually schedule — a queued job and a console command — are adapters, and they live here because this is the crate that has both.

// src/routes/console.rs
pub fn schedule(schedule: &mut Schedule) {
    schedule.job(PruneSessions).daily_at("03:00").without_overlapping(HALF_HOUR);
    schedule.command("app:seed").weekly_on(1, "04:00").on_one_server();
    schedule.call("heartbeat", |_| Box::pin(async { Ok(()) })).every_five_minutes();
}
