Enum DispatchQoS 

pub enum DispatchQoS {
    Background = 0,
    Utility = 1,
    Default = 2,
    UserInitiated = 3,
    UserInteractive = 4,
}

Quality of Service levels for dispatch queues

These QoS levels help the system prioritize work appropriately.

Examples

use apple_cf::dispatch_queue::{DispatchQueue, DispatchQoS};

// High priority for UI-affecting work
let queue = DispatchQueue::new("com.myapp.ui", DispatchQoS::UserInteractive);

// Lower priority for background tasks
let bg_queue = DispatchQueue::new("com.myapp.background", DispatchQoS::Background);

Variants

Background = 0

Background QoS - for maintenance or cleanup tasks

Utility = 1

Utility QoS - for tasks that may take some time

Default = 2

Default QoS - standard priority

UserInitiated = 3

User Initiated QoS - for tasks initiated by the user

UserInteractive = 4

User Interactive QoS - for tasks that affect the UI

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<(), Error>

Formats the value using the given formatter.

impl Default for DispatchQoS

fn default() -> DispatchQoS

Returns the “default value” for a type.

impl Hash for DispatchQoS

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

where __H: Hasher,

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 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.
