Struct ydb_grpc::generated::ydb::topic::stream_read_message::read_response::Batch

pub struct Batch {
    pub message_data: Vec<MessageData>,
    pub producer_id: String,
    pub write_session_meta: HashMap<String, String>,
    pub codec: i32,
    pub written_at: Option<Timestamp>,
}

Representation of sequence of client messages from one write session.

Fields

message_data: Vec<MessageData>

List of client messages.

producer_id: String

Producer identifier provided by client for this batch of client messages.

write_session_meta: HashMap<String, String>

Client metadata attached to write session, the same for all messages in batch.

codec: i32

Codec that is used for data compression. See enum Codec above for values.

written_at: Option<Timestamp>

Persist timestamp on server for batch.

Trait Implementations

impl Clone for Batch

fn clone(&self) -> Batch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Batch

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

Formats the value using the given formatter.

impl Default for Batch

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Batch

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
__D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Batch

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>where
B: BufMut,
Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>where
Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>where
B: BufMut,
Self: Sized,

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

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>where
Self: Sized,

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

fn decode<B>(buf: B) -> Result<Self, DecodeError>where
B: Buf,
Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>where
B: Buf,
Self: Default,

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

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>where
B: Buf,
Self: Sized,

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

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>where
B: Buf,
Self: Sized,

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

impl PartialEq<Batch> for Batch

fn eq(&self, other: &Batch) -> 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.

impl Serialize for Batch

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
__S: Serializer,

Serialize this value into the given Serde serializer.
