Enum PriorityDirection 

pub enum PriorityDirection {
    BiggerIsMoreUrgent,
    SmallerIsMoreUrgent,
}

Which way a kernel’s raw priority numbers run.

TierSpec::priority is RAW — the number the system author wrote in [tiers.<name>.<rtos>].priority, already in the target kernel’s scale — so only the board knows which end is urgent. Issue 0636.

Variants

BiggerIsMoreUrgent

NuttX (1..=255), FreeRTOS (0..=7), POSIX SCHED_FIFO: bigger wins.

SmallerIsMoreUrgent

Zephyr (negative = cooperative), ThreadX (0..=31): smaller wins.

Trait Implementations

impl Clone for PriorityDirection

fn clone(&self) -> PriorityDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PriorityDirection

impl Debug for PriorityDirection

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

Formats the value using the given formatter.

impl Eq for PriorityDirection

impl PartialEq for PriorityDirection

fn eq(&self, other: &PriorityDirection) -> 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.
