pub struct UnboundedSender<T>(/* private fields */);
Expand description

The transmission end of an unbounded mpsc channel.

This value is created by the unbounded function.

Implementations§

source§

impl<T> UnboundedSender<T>

source

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

Check if the channel is ready to receive a message.

source

pub fn is_closed(&self) -> bool

Returns whether this channel is closed without needing a context.

source

pub fn close_channel(&self)

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

source

pub fn disconnect(&mut self)

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

source

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

Send a message on the channel.

This method should only be called after poll_ready has been used to verify that the channel is ready to receive a message.

source

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

Sends a message along this channel.

This is an unbounded sender, so this function differs from Sink::send by ensuring the return type reflects that the channel is always ready to receive messages.

source

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

Returns whether the senders send to the same receiver.

source

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

Returns whether the sender send to this receiver.

source

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

Hashes the receiver into the provided hasher

source

pub fn len(&self) -> usize

Return the number of messages in the queue or 0 if channel is disconnected.

source

pub fn is_empty(&self) -> bool

Return false is channel has no queued messages, true otherwise.
