Enumeration Type Documentation

Priority

enum class roo_scheduler::Priority

strong

Priority controls dispatch order among eligible tasks.

Higher-priority tasks execute first. Tasks with equal priority execute in FIFO order.

Priority does not affect scheduling time; it only affects dispatch order once tasks are already eligible.

If tasks are sufficiently spread out in time and complete quickly, they are effectively dispatched by due time regardless of priority.

Priority is captured when execution is scheduled and remains fixed for that scheduled execution. Re-scheduling may assign a different priority.

delay() and delayUntil() guarantee execution of tasks whose priority is at least the requested minimum. Lower-priority overdue tasks may remain pending.
