Implementations

impl Handle

impl Handle

pub(crate) fn spawn<F>( me: &Arc<Self>, future: F, id: Id, spawned_at: SpawnLocation, ) -> JoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a future onto the thread pool

impl Handle

pub(super) fn trace_core(&self, core: Box<Core>) -> Box<Core>

impl Handle

pub(super) fn schedule_task(&self, task: Notified<Arc<Handle>>, is_yield: bool)

pub(super) fn schedule_option_task_without_yield( &self, task: Option<Notified<Arc<Handle>>>, )

fn push_remote_task(&self, task: Notified<Arc<Handle>>)

pub(super) fn close(&self)

fn notify_parked_local(&self) -> bool

Notify a parked worker.

Returns true if a worker was notified, false otherwise.

fn notify_parked_remote(&self)

pub(super) fn notify_all(&self)

fn notify_if_work_pending(&self)

fn transition_worker_from_searching(&self) -> bool

Returns true if another parked worker was notified, false otherwise.

fn shutdown_core(&self, core: Box<Core>)

Signals that a worker has observed the shutdown signal and has replaced its core back into its handle.

If all workers have reached this point, the final cleanup is performed.

fn ptr_eq(&self, other: &Handle) -> bool
