Struct Stream Processor &nbsp; Copy item path

impl<T, A, W, Tr> StreamProcessor<T, A, W, Tr>
where A: Aggregator<Input = f64, Output = f64> + Clone + Send + Sync + 'static, W: WindowAssigner + Clone + Send + Sync + 'static, Tr: WindowTrigger + Clone + Send + Sync + 'static,

pub fn new<F>( config: StreamProcessorConfig, assigner: W, trigger: Tr, aggregator_factory: F, ) -> Self
where F: Fn(&str) -> A + Send + Sync + 'static,

Create a new stream processor

pub async fn process_event( &self, key: String, event_time: DateTime<Utc>, value: f64, ) -> Result<(), ProcessorError>

Process a single event

This is the main entry point for event processing. It:

Assigns the event to windows
Updates aggregators for each window
Updates watermark
Checks for windows ready to fire
Emits results for completed windows

pub fn results(&mut self) -> Option<impl Stream<Item = WindowResult>>

Get a stream of window results

pub async fn stats(&self) -> ProcessorStats

Get current statistics

pub async fn cleanup(&self) -> Result<usize, ProcessorError>

Trigger cleanup of old windows

pub async fn reset(&self)

Reset the processor (for testing)
