impl ConsumerContext for DefaultConsumerContext

source§

fn rebalance( &self, native_client: &NativeClient, err: RDKafkaRespErr, tpl: &mut TopicPartitionList )

Implements the default rebalancing strategy and calls the pre_rebalance and post_rebalance methods. If this method is overridden, it will be responsibility of the user to call them if needed.
source§

fn pre_rebalance<'a>(&self, rebalance: &Rebalance<'a>)

Pre-rebalance callback. This method will run before the rebalance and should terminate its execution quickly.
source§

fn post_rebalance<'a>(&self, rebalance: &Rebalance<'a>)

Post-rebalance callback. This method will run after the rebalance and should terminate its execution quickly.
source§

fn commit_callback(&self, result: KafkaResult<()>, offsets: &TopicPartitionList)

Post commit callback. This method will run after a group of offsets was committed to the offset store.
source§
