Implementations

impl EventLoop

pub fn new(options: MqttOptions, cap: usize) -> EventLoop

New MQTT EventLoop

When connection encounters critical errors (like auth failure), user has a choice to access and update options, state and requests.

pub fn handle(&self) -> Sender<Request>

Returns a handle to communicate with this eventloop

pub async fn poll( &mut self ) -> impl Future<Output = Result<Event, ConnectionError>>

Yields Next notification or outgoing request and periodically pings the broker. Continuing to poll will reconnect to the broker if there is a disconnection. NOTE Don’t block this while iterating
