Struct StreamMessage 

pub struct StreamMessage {
    pub request_id: u64,
    pub msg_id: Option<MsgId>,
    pub payload: Vec<u8>,
    pub publish_time: u64,
    pub producer_name: String,
    pub subscription_name: String,
    pub attributes: HashMap<String, String>,
}

The message that is sent by producer to topic and then to consumer

Fields

request_id: u64

Unique ID for tracking the message request

msg_id: Option<MsgId>

Identifies the message, associated with a unique topic, subscription and the broker

payload: Vec<u8>

The actual payload of the message

publish_time: u64

Timestamp for when the message was published

producer_name: String

Identifies the producer’s name

subscription_name: String

Subscription name the consumer is subscribed to

attributes: HashMap<String, String>

User-defined properties/attributes

Trait Implementations

impl Clone for StreamMessage

fn clone(&self) -> StreamMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamMessage

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

Formats the value using the given formatter.

impl Default for StreamMessage

fn default() -> Self

Returns the “default value” for a type.

impl From<StreamMessage> for StreamMessage

fn from(proto_stream_msg: ProtoStreamMessage) -> Self

Converts to this type from the input type.

impl From<StreamMessage> for StreamMessage

fn from(stream_msg: StreamMessage) -> Self

Converts to this type from the input type.

impl Message for StreamMessage

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 StreamMessage

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

Tests for self and other values to be equal, and is used by ==.

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

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