Struct SeaMessage 

pub struct SeaMessage { /* private fields */ }

A message delivered by one of this crate’s subscribers.

This is the whole delivery on standard input; a stream file wraps it in a FileMessage, which adds the subscription’s reposition handle.

The transport keeps no consumer positions (its resumable mode is unimplemented upstream), so acknowledgement reports AckError::Unsupported rather than pretending; resume explicitly via the descriptor’s start position or a captured FilePosition.

Implementations

impl SeaMessage

pub fn stream(&self) -> &str

The stream key this message was published to.

Trait Implementations

impl Debug for SeaMessage

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

Formats the value using the given formatter.

impl IncomingMessage for SeaMessage

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 decode_error(&self) -> Option<&CodecError>

The error the broker met while reading this delivery, or None when it read the delivery whole.

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.

impl Positioned for SeaMessage

type Position = FilePosition

The position type, matching the subscription’s Seeker::Position.

fn position(&self) -> FilePosition

Returns the position of this delivery; seeking to it redelivers this message.
