Struct LiveUpdates 

Source 
pub struct LiveUpdates<Q> { /* private fields */ }
Expand description

Polls the database for job and queue changes and pushes them to WebSocket clients.

Implementations§

Source§

impl<Q: JobHistory + 'static> LiveUpdates<Q>

Source

pub fn new( queue: Arc<Q>, websocket: Arc<RwLock<WebSocketState>>, max_jobs: u32, ) -> Self

Live updates from queue to the clients of websocket, reading at most max_jobs changed jobs per poll.

Source

pub fn spawn(self, interval: Duration) -> JoinHandle<()> ⓘ

Poll every interval in a background task. A failed poll is logged and retried at the next interval.

Source

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

Push the changes since the previous poll. Does nothing (and forgets what was sent) while no client is connected.
