Implementations

impl<T> BoundedSenderInner<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 do_send_b(&mut self, msg: T) -> Result<(), TrySendError<T>>

fn queue_push_and_signal(&self, msg: T)

fn inc_num_messages(&self) -> Option<usize>

fn park(&mut self)

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

Returns whether the senders send to the same receiver.

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

Returns whether the sender send to this receiver.

fn ptr(&self) -> *const BoundedInner<T>

Returns pointer to the Arc containing sender

The returned pointer is not referenced and should be only used for hashing!

fn is_closed(&self) -> bool

Returns whether this channel is closed without needing a context.

fn close_channel(&self)

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

fn poll_unparked(&mut self, cx: Option<&mut Context<'_>>) -> Poll<()>
