pub type OutcomeSender = Sender<(TaskGroup, TaskOutcome)>;

Channel sender for task outcomes

Aliased Type

struct OutcomeSender(/* private fields */);

Implementations

impl<T> Sender<T>

pub fn try_send(&mut self, msg: T) -> Result<(), TrySendError<T>>

Attempts to send a message on this Sender, returning the message if there was an error.

pub fn start_send(&mut self, msg: T) -> Result<(), SendError>

Send a message on the channel.

This function should only be called after poll_ready has reported that the channel is ready to receive a message.

pub fn poll_ready( &mut self, cx: &mut Context<'_> ) -> Poll<Result<(), SendError>>

Polls the channel to determine if there is guaranteed capacity to send at least one item without waiting.

Return value

This method returns:

• Poll::Ready(Ok(_)) if there is sufficient capacity;
• Poll::Pending if the channel may not have capacity, in which case the current task is queued to be notified once capacity is available;
• Poll::Ready(Err(SendError)) if the receiver has been dropped.

pub fn is_closed(&self) -> bool

Returns whether this channel is closed without needing a context.

pub fn close_channel(&mut self)

Closes this channel from the sender side, preventing any new messages.

pub fn disconnect(&mut self)

Disconnects this sender from the channel, closing it if there are no more senders left.

pub fn same_receiver(&self, other: &Sender<T>) -> bool

Returns whether the senders send to the same receiver.

pub fn is_connected_to(&self, receiver: &Receiver<T>) -> bool

Returns whether the sender send to this receiver.

pub fn hash_receiver<H>(&self, hasher: &mut H)where H: Hasher,

Hashes the receiver into the provided hasher

Trait Implementations

impl<T> Clone for Sender<T>

fn clone(&self) -> Sender<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Sender<T>

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

Formats the value using the given formatter.

impl<E> GhostChannelSender<E> for Sender<E>where E: GhostEvent,

fn ghost_actor_channel_send( &self, event: E ) -> MustBoxFuture<'static, Result<(), GhostError>>

Forward a GhostEvent along this channel.

impl<T> Sink<T> for Sender<T>

type Error = SendError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Sender<T>>, cx: &mut Context<'_> ) -> Poll<Result<(), <Sender<T> as Sink<T>>::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut Sender<T>>, msg: T ) -> Result<(), <Sender<T> as Sink<T>>::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Sender<T>>, cx: &mut Context<'_> ) -> Poll<Result<(), <Sender<T> as Sink<T>>::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Sender<T>>, _: &mut Context<'_> ) -> Poll<Result<(), <Sender<T> as Sink<T>>::Error>>

Flush any remaining output and close this sink, if necessary.
