Struct ZmqMessage 

pub struct ZmqMessage { /* private fields */ }

A message delivered by one of the transport’s subscribers.

Delivery is at most once and there is no durability, so acknowledgement is reported as AckError::Unsupported rather than emulated.

Implementations

impl ZmqMessage

pub fn name(&self) -> &str

The name frame this message carried.

Trait Implementations

impl Debug for ZmqMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IncomingMessage for ZmqMessage

fn payload(&self) -> &[u8]

Returns the raw payload of the message.

fn headers(&self) -> &HeaderMap

Returns the headers attached to the message.

fn ack(self) -> impl Future<Output = Result<(), AckError>>

Acknowledges successful processing. Consumes the message handle.

fn nack(self, _requeue: bool) -> impl Future<Output = Result<(), AckError>>

Negatively acknowledges the message. When requeue is true the broker should redeliver according to its own retry policy; when false it should drop or dead-letter the message.

fn partition_key(&self) -> Option<&[u8]>

Returns the routing key the broker partitioned this message by, or None when the message carries no key.

fn redelivery_count(&self) -> Option<u64>

How many times the broker has delivered this message, counting this delivery. None where the transport counts nothing.

fn supports_nack_after(&self) -> bool

Reports whether this transport can honor nack_after natively.

fn nack_after( self, delay: Duration, ) -> impl Future<Output = Result<(), AckError>> + Send

where Self: Sized,

Negatively acknowledges the message, asking the broker to redeliver it no sooner than delay from now.
