Enum Priority 

#[repr(u8)]
pub enum Priority {
    Critical = 0,
    High = 1,
    Normal = 2,
    Low = 3,
}

Priority class. Lower discriminant = more important.

Classes set the base of a task’s effective score; waiting time adds a capped aging bonus and deadlines add urgency (see PriorityConfig and UrgencyConfig).

Variants

Critical = 0

Work that must run before anything else (alerts, interactive critical paths).

High = 1

Latency-sensitive work (interactive requests).

Normal = 2

Regular work (the default).

Low = 3

Background work that runs when nothing more important is waiting.

Implementations

impl Priority

pub const ALL: [Priority; 4]

All classes, most important first.

pub const COUNT: usize = 4

Number of classes.

pub fn index(self) -> usize

Position in Priority::ALL (0 = Critical).

pub fn from_index(i: usize) -> Option<Priority>

The class at i in Priority::ALL.

pub fn name(self) -> &'static str

Lowercase name ("critical", "high", "normal", "low").

Trait Implementations

impl Clone for Priority

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Priority

impl Debug for Priority

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

Formats the value using the given formatter.

impl Default for Priority

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Priority

impl Hash for Priority

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Priority

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Priority

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Priority

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
