[−][src]Function pulsar_sys::pulsar_consumer_negative_acknowledge
pub unsafe extern "C" fn pulsar_consumer_negative_acknowledge(
consumer: *mut pulsar_consumer_t,
message: *mut pulsar_message_t
)
Acknowledge the failure to process a single message.
When a message is "negatively acked" it will be marked for redelivery after some fixed delay. The delay is configurable when constructing the consumer with {@link ConsumerConfiguration#setNegativeAckRedeliveryDelayMs}.
This call is not blocking.
@param message The {@code Message} to be acknowledged
