pub struct Sender<T>(_);
Expand description

The transmission end of a bounded mpsc channel.

This value is created by the channel function.

Implementations

Attempts to send a message on this Sender, returning the message if there was an error.

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.

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.

Returns whether this channel is closed without needing a context.

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

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

Returns whether the senders send to the same receiver.

Returns whether the sender send to this receiver.

Hashes the receiver into the provided hasher
