Struct tokio_nsq::NSQConsumer

source · [−]

pub struct NSQConsumer { /* private fields */ }

Expand description

An NSQD consumer corresponding to multiple NSQD instances.

A consumer will automatically restart and maintain connections to multiple NSQD instances. As connections die, and restart REQ will automatically be rebalanced to the active connections.

Implementations

impl NSQConsumer

pub async fn consume(&mut self) -> Option<NSQEvent>

Consume events from NSQ connections including status events.

pub async fn consume_filtered(&mut self) -> Option<NSQMessage>

Consume events from NSQ connections ignoring all connection status events.

pub fn is_starved(&mut self) -> bool

Indicates if any connections are blocked on processing before being able to receive more messages. This can be useful for determining when to process a batch of messages.
