impl<T> Sender<T>

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.

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.

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.

fn is_closed(&self) -> bool

fn same_receiver(&self, other: &Self) -> bool

Returns whether the senders send to the same receiver.

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

Returns whether the sender send to this receiver.

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