Enum Priority 

pub enum Priority {
    Low,
    Normal,
    High,
    Custom(u32),
}

Priority level for tasks

Ordering is based on weight values: Low (10) < Normal (50) < High (100). Custom(w) is ordered by its weight value relative to the standard priorities.

Example

use reinhardt_tasks::Priority;

let high = Priority::High;
let normal = Priority::Normal;
let low = Priority::Low;
assert!(high > normal);
assert!(normal > low);

// Custom priority is ordered by weight value
let custom_75 = Priority::Custom(75);
assert!(custom_75 > normal);  // 75 > 50
assert!(custom_75 < high);    // 75 < 100

let custom_200 = Priority::Custom(200);
assert!(custom_200 > high);   // 200 > 100

Variants

Low

Low priority (weight: 10)

Normal

Normal priority (weight: 50)

High

High priority (weight: 100)

Custom(u32)

Custom priority with specified weight

Implementations

impl Priority

pub fn default_weight(&self) -> u32

Get the default weight for this priority

Example

use reinhardt_tasks::Priority;

assert_eq!(Priority::High.default_weight(), 100);
assert_eq!(Priority::Normal.default_weight(), 50);
assert_eq!(Priority::Low.default_weight(), 10);
assert_eq!(Priority::Custom(75).default_weight(), 75);

Trait Implementations

impl Clone for Priority

fn clone(&self) -> Priority

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Priority

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

Formats the value using the given formatter.

impl Default for Priority

fn default() -> Priority

Returns the “default value” for a type.

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.

impl PartialEq for Priority

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

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.
