Enum SchedPolicy

}

Per-thread OS scheduling policy.

Fifo / RoundRobin / Deadline / Sporadic map to platform- native scheduling classes when available. Platform(...) is the escape hatch for RTOS-specific knobs (e.g. ThreadX preempt- threshold) that don’t map cleanly into the portable variants.

User-facing API (Executor::open_threaded) takes the abstract Priority-like values and PlatformScheduler translates them into platform-native numerics — direction-flipped priority (Zephyr / ThreadX low-numeric = high-priority vs POSIX / FreeRTOS high-numeric = high-priority) handled internally. Phase 110.D.

Variants

Fifo

POSIX SCHED_FIFO. os_pri is the platform-native numeric priority; out-of-range values surface SchedError::OutOfRange.

Fields

os_pri: u8

RoundRobin

POSIX SCHED_RR with quantum_ms time slice.

Fields

os_pri: u8

quantum_ms: u32

Deadline

Linux SCHED_DEADLINE (sched_setattr). All values nanoseconds.

Fields

runtime_ns: u64

period_ns: u64

deadline_ns: u64

Sporadic

NuttX SCHED_SPORADIC server. Phase 110.E.

Fields

budget_us: u32

period_us: u32

hi_pri: u8

lo_pri: u8

Trait Implementations

impl Clone for SchedPolicy

fn clone(&self) -> SchedPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SchedPolicy

impl Debug for SchedPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SchedPolicy

impl PartialEq for SchedPolicy

fn eq(&self, other: &SchedPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
