Struct DispatchQos 

pub struct DispatchQos {
    pub qos_class: DispatchQosClass,
    pub relative_priority: i32,
}

The quality of service, or the execution priority, to apply to tasks.

This is semantically equivalent to Swift’s DispatchQoS.

Fields

qos_class: DispatchQosClass

The quality-of-service class.

relative_priority: i32

The priority of a quality of service relative to others with the same class.

Implementations

impl DispatchQos

pub const INTERACTIVE: Self

The quality-of-service class for user-interactive tasks, such as animations, event handling, or updating your app’s user interface.

pub const USER_INITIATED: Self

The quality-of-service class for tasks that prevent the user from actively using your app.

pub const DEFAULT: Self

The default quality-of-service class.

pub const UTILITY: Self

The quality-of-service class for tasks that the user does not track actively.

pub const BACKGROUND: Self

The quality-of-service class for maintenance or cleanup tasks that you create.

pub const UNSPECIFIED: Self

The absence of a quality-of-service class.

pub const fn new(qos_class: DispatchQosClass, relative_priority: i32) -> Self

Creates a new instance with the specified QoS class and relative priority.

pub const fn with_qos_class(self, qos_class: DispatchQosClass) -> Self

Reassigns the value of qos_class.

pub const fn with_relative_priority(self, relative_priority: i32) -> Self

Reassigns the value of relative_priority.

Trait Implementations

impl Clone for DispatchQos

fn clone(&self) -> DispatchQos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DispatchQos

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

Formats the value using the given formatter.

impl Default for DispatchQos

fn default() -> Self

Returns the “default value” for a type.

impl Hash for DispatchQos

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 DispatchQos

fn cmp(&self, other: &DispatchQos) -> 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 DispatchQos

fn eq(&self, other: &DispatchQos) -> 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 DispatchQos

fn partial_cmp(&self, other: &DispatchQos) -> 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.
