Struct PeriodicTask 

pub struct PeriodicTask {
    pub period_us: u64,
    pub budget_us: u64,
    pub priority: Priority,
    /* private fields */
}

Periodic task specification

A task may carry a run function pointer that is invoked by RateMonotonicScheduler::schedule when the task becomes ready. Tasks created without a runner (via PeriodicTask::new) only advance their period bookkeeping when scheduled; use PeriodicTask::with_runner or RateMonotonicScheduler::schedule_with to run real work.

Fields

period_us: u64

Period in microseconds

budget_us: u64

Execution time budget in microseconds

priority: Priority

Priority

Implementations

impl PeriodicTask

pub const fn new(period_us: u64, budget_us: u64, priority: Priority) -> Self

Create a new periodic task without an attached runner

When scheduled, such a task only advances its period bookkeeping and records a zero-duration execution. Attach work with PeriodicTask::with_runner or drive execution through RateMonotonicScheduler::schedule_with.

pub const fn with_runner( period_us: u64, budget_us: u64, priority: Priority, run: fn(), ) -> Self

Create a new periodic task with an attached runner function

The run function is executed by RateMonotonicScheduler::schedule each time the task becomes ready, and its wall-clock duration is recorded in the task statistics (including deadline-miss detection against budget_us).

pub fn runner(&self) -> Option<fn()>

Get the attached runner, if any

pub fn is_ready(&self, current_us: u64) -> bool

Check if task is ready to execute

pub fn mark_executed(&mut self, current_us: u64)

Mark task as executed

pub fn next_deadline(&self) -> Deadline

Get deadline for next execution
