Struct google_api_proto::google::pubsub::v1::ReceivedMessage

pub struct ReceivedMessage {
    pub ack_id: String,
    pub message: Option<PubsubMessage>,
    pub delivery_attempt: i32,
}

A message and its corresponding acknowledgment ID.

Fields

ack_id: String

Optional. This ID can be used to acknowledge the received message.

message: Option<PubsubMessage>

Optional. The message.

delivery_attempt: i32

Optional. The approximate number of times that Pub/Sub has attempted to deliver the associated message to a subscriber.

More precisely, this is 1 + (number of NACKs) + (number of ack_deadline exceeds) for this message.

A NACK is any call to ModifyAckDeadline with a 0 deadline. An ack_deadline exceeds event is whenever a message is not acknowledged within ack_deadline. Note that ack_deadline is initially Subscription.ackDeadlineSeconds, but may get extended automatically by the client library.

Upon the first delivery of a given message, delivery_attempt will have a value of 1. The value is calculated at best effort and is approximate.

If a DeadLetterPolicy is not set on the subscription, this will be 0.

Trait Implementations

impl Clone for ReceivedMessage

fn clone(&self) -> ReceivedMessage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReceivedMessage

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

Formats the value using the given formatter.

impl Default for ReceivedMessage

fn default() -> Self

Returns the “default value” for a type.

impl Message for ReceivedMessage

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ReceivedMessage

fn eq(&self, other: &ReceivedMessage) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
