Struct MultiTopicReceiver

Source 
pub struct MultiTopicReceiver<T: Eq + Hash + Clone, M: Clone> { /* private fields */ }
Expand description

A multi-topic receiver that listens to messages from multiple topics.

§Type Parameters

  • T: The type representing a topic.
  • M: The message type being received.

Implementations§

Source§

impl<T: Eq + Hash + Clone, M: Clone> MultiTopicReceiver<T, M>

Source

pub fn new(subscribers: Arc<DashMap<T, Sender<M>>>) -> Self

Creates a new MultiTopicReceiver for the given TopicStream.

§Arguments
  • subscribers: A reference to the DashMap containing the active subscribers.
§Returns

A new MultiTopicReceiver instance.

Source

pub fn subscribe(&mut self, topics: &[T])

Subscribes to the given list of topics. If already subscribed to a topic, it is ignored.

§Arguments
  • topics: A slice of topics to subscribe to.
Source

pub async fn recv(&mut self) -> Option<M>

An Option containing the received message, or None if all receivers are closed.
