Struct rdkafka::producer::base_producer::ThreadedProducer

#[must_use = "The threaded producer will stop immediately if unused"]
pub struct ThreadedProducer<C: ProducerContext + 'static> { /* fields omitted */ }

A producer with a separate thread for event handling.

The ThreadedProducer is a BaseProducer with a separate thread dedicated to calling poll at regular intervals in order to execute any queued event, such as delivery notifications. The thread will be automatically stopped when the producer is dropped.

Methods

impl<C: ProducerContext + 'static> ThreadedProducer<C>

pub fn send<'a, K: ?Sized, P: ?Sized>(     &self,     record: BaseRecord<'a, K, P, C::DeliveryOpaque> ) -> Result<(), (KafkaError, BaseRecord<'a, K, P, C::DeliveryOpaque>)> where     K: ToBytes,     P: ToBytes,

Sends a message to Kafka. See the documentation in BaseProducer.

pub fn poll<T: Into<Option<Duration>>>(&self, timeout: T)

Polls the internal producer. This is not normally required since the ThreadedProducer had a thread dedicated to calling poll regularly.

pub fn flush<T: Into<Option<Duration>>>(&self, timeout: T)

Flushes the producer. Should be called before termination.

pub fn in_flight_count(&self) -> i32

Returns the number of messages waiting to be sent, or send but not acknowledged yet.
