Struct TaskQueue 

pub struct TaskQueue<B: QueueBacking> { /* private fields */ }

Sends ordered tasks to a pool for background processing.

Implementations

impl<B: PushPopQueueBacking> TaskQueue<B>

pub fn join<T>(&self, task: impl TaskCollection<T>) -> T

Joins the pool in executing the given task. Both the current thread and the background threads complete the task’s work. Semantically, this is equivalent to calling spawn(task).join(), but is more efficient by ensuring that the present thread always receives at least one work item.

pub fn spawn<T>(&self, task: impl TaskCollection<T>) -> Task<T, B>

Spawns a new task into the queue.

impl<P: Ord + Send + Sync> TaskQueue<Priority<P>>

pub fn join<T>(&self, priority: P, task: impl TaskCollection<T>) -> T

Joins the pool in executing the given task. Both the current thread and the background threads complete the task’s work. Semantically, this is equivalent to calling spawn(task).join(), but is more efficient by ensuring that the present thread always receives at least one work item.

pub fn spawn<T>( &self, priority: P, task: impl TaskCollection<T>, ) -> Task<T, Priority<P>>

Spawns a new task into the queue, with the given priority.
