Struct Task

pub struct Task { /* private fields */ }

Wrapper for a Future that can be polled by an external single threaded Dart executor.

Implementations

impl Task

pub fn spawn(future: LocalBoxFuture<'static, ()>)

Spawns a new Task that will drive the given Future.

Must be called on the same thread where the Task will be polled, otherwise polling will panic.

pub fn poll(&self)

Polls the underlying Future.

Polling after Future’s completion is no-op.

Panics

If called not on the same thread where this Task was originally created.

Trait Implementations

impl ArcWake for Task

fn wake_by_ref(arc_self: &Arc<Self>)

Commands an external Dart executor to poll this Task if it’s incomplete and there are no Poll::Pending awake requests already.

fn wake(self: Arc<Self>)

Indicates that the associated task is ready to make progress and should be polled.

impl Debug for Task

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

Formats the value using the given formatter.

impl Send for Task

Task can be sent across threads safely because it ensures that the underlying Future will only be touched from a single thread it was created on.

impl Sync for Task

Task can be shared across threads safely because it ensures that the underlying Future will only be touched from a single thread it was created on.
