Struct holochain_websocket::ListenerHandle

pub struct ListenerHandle { /* fields omitted */ }

Handle for shutting down a listener stream.

Example

use futures::stream::StreamExt;
use holochain_websocket::*;
use url2::url2;

#[tokio::main]
async fn main() {
    let (listener_handle, mut listener_stream) = WebsocketListener::bind_with_handle(
        url2!("ws://127.0.0.1:12345"),
        std::sync::Arc::new(WebsocketConfig::default()),
    )
    .await
    .unwrap();

    tokio::spawn(async move { while let Some(Ok(_)) = listener_stream.next().await {} });
    listener_handle.close();
}

Implementations

impl ListenerHandle

pub fn close(self)

Shutdown the listener stream.

pub fn local_addr(&self) -> &Url2

Get the url of the bound local listening socket.

pub fn get_config(&self) -> Arc<WebsocketConfig>

Get the config associated with this listener.

pub async fn close_on<F>(self, f: F) where
    F: Future<Output = bool>, 

Close the listener when the future resolves to true. If the future returns false the listener will not be closed.

 tokio::spawn(async move { while let Some(Ok(_)) = listener_stream.next().await {} });
 let (tx, rx) = tokio::sync::oneshot::channel();
 tokio::task::spawn(listener_handle.close_on(async move { rx.await.unwrap_or(true) }));
 tx.send(true).unwrap();
