Trait ostd::task::Scheduler

pub trait Scheduler: Sync + Send {
    // Required methods
    fn enqueue(&self, task: Arc<Task>);
    fn dequeue(&self) -> Option<Arc<Task>>;
    fn should_preempt(&self, task: &Arc<Task>) -> bool;
}

fn enqueue(&self, task: Arc<Task>)

Enqueues a task to the scheduler.

fn dequeue(&self) -> Option<Arc<Task>>

Dequeues a task from the scheduler.

fn should_preempt(&self, task: &Arc<Task>) -> bool
