Struct futures::channel::mpsc::UnboundedSender

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: &UnboundedSender<T>) -> 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
