pub fn try_send(&mut self, msg: T) -> Result<(), TrySendError<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>
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>>
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::Pendingif 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 close_channel(&mut self)
pub fn close_channel(&mut self)
Closes this channel from the sender side, preventing any new messages.
pub fn disconnect(&mut self)
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
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
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,
pub fn hash_receiver<H>(&self, hasher: &mut H)where
H: Hasher,
Hashes the receiver into the provided hasher
