pub struct UnboundedSender<T>(_);Expand description
The transmission end of an unbounded mpsc channel.
This value is created by the unbounded function.
Implementations
sourceimpl<T> UnboundedSender<T>
impl<T> UnboundedSender<T>
sourcepub fn poll_ready(&self, &mut Context<'_>) -> Poll<Result<(), SendError>>
pub fn poll_ready(&self, &mut Context<'_>) -> Poll<Result<(), SendError>>
Check if the channel is ready to receive a message.
sourcepub fn is_closed(&self) -> bool
pub fn is_closed(&self) -> bool
Returns whether this channel is closed without needing a context.
sourcepub fn close_channel(&self)
pub fn close_channel(&self)
Closes this channel from the sender side, preventing any new messages.
sourcepub fn disconnect(&mut self)
pub fn disconnect(&mut self)
Disconnects this sender from the channel, closing it if there are no more senders left.
sourcepub 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 method should only be called after poll_ready has been used to
verify that the channel is ready to receive a message.
sourcepub fn unbounded_send(&self, msg: T) -> Result<(), TrySendError<T>>
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.
sourcepub fn same_receiver(&self, other: &UnboundedSender<T>) -> bool
pub fn same_receiver(&self, other: &UnboundedSender<T>) -> bool
Returns whether the senders send to the same receiver.
sourcepub fn is_connected_to(&self, receiver: &UnboundedReceiver<T>) -> bool
pub fn is_connected_to(&self, receiver: &UnboundedReceiver<T>) -> bool
Returns whether the sender send to this receiver.
sourcepub 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
