Enum dispatch::QueuePriority

pub enum QueuePriority {
    High,
    Default,
    Low,
    Background,
}

The priority of a global concurrent queue.

Variants

High

The queue is scheduled for execution before any default priority or low priority queue.

Default

The queue is scheduled for execution after all high priority queues, but before any low priority queues.

Low

The queue is scheduled for execution after all default priority and high priority queues.

Background

The queue is scheduled for execution after all high priority queues have been scheduled. The system runs items on a thread whose priority is set for background status and any disk I/O is throttled to minimize the impact on the system.

Trait Implementations

impl Clone for QueuePriority

fn clone(&self) -> QueuePriority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueuePriority

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

Formats the value using the given formatter.

impl Hash for QueuePriority

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 PartialEq<QueuePriority> for QueuePriority

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
