pub struct Channel { /* private fields */ }
Expand description

A protocol channel.

This is the handle that can be sent to other threads.

Implementations§

source§

impl Channel

source

pub fn discovery_key(&self) -> &[u8; 32]

Get the discovery key of this channel.

source

pub fn key(&self) -> &[u8; 32]

Get the key of this channel.

source

pub fn id(&self) -> usize

Get the local wire ID of this channel.

source

pub fn closed(&self) -> bool

Check if the channel is closed.

source

pub async fn send(&mut self, message: Message) -> Result<()>

Send a message over the channel.

source

pub async fn send_batch(&mut self, messages: &[Message]) -> Result<()>

Send a batch of messages over the channel.

source

pub fn take_receiver(&mut self) -> Option<Receiver<Message>>

Take the receiving part out of the channel.

After taking the receiver, this Channel will not emit messages when polled as a stream. The returned receiver will.

source

pub fn local_sender(&mut self) -> Sender<Message>

Clone the local sending part of the channel receiver. Useful for direct local communication to the channel listener. Typically you will only want to send a LocalSignal message with this sender to make it clear what event came from the remote peer and what was local signaling.

source

pub async fn close(&mut self) -> Result<()>

Send a close message and close this channel.

source

pub async fn signal_local_protocol( &mut self, name: &str, data: Vec<u8> ) -> Result<()>

Signal the protocol to produce Event::LocalSignal. If you want to send a message to the channel level, see take_receiver() and local_sender().
