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.
