macro_rules! register_task {
    ($name:ident, priority = $prio:expr, poll_fn = $poll:expr, completed = $completed:expr, buf = $buf:expr) => { ... };
}

Convenience macro to declare a task registration by hand (used internally by #[rivet::task], and available for advanced manual use).

rivet::register_task!(MY_TASK, priority = 1, poll_fn = my_poll, buf = MY_BUF);
