Fields

commit_time: Option<Timestamp>

The timestamp in which the change was committed.

record_sequence: String

The sequence number for the record within the transaction.

transaction_id: String

A globally unique string that represents the transaction in which the change was committed.

is_last_record: bool

Indicates whether this is the last record for a transaction in the current partition.

table: String

Name of the table affected by the change.

column_types: Vec<ColumnType>

Column types defined in the schema.

mods: Vec<Mod>

Changes made in the transaction.

mod_type: String

Describes the type of change. One of INSERT, UPDATE or DELETE.

value_capture_type: String

One of value capture type: NEW_VALUES, OLD_VALUES, OLD_AND_NEW_VALUES.

record_count: i64

Number of records in transactions.

partition_count: i64

Number of partitions in transactions.

transaction_tag: String

Transaction tag info.

is_system_transaction: bool

Trait Implementations

impl Clone for DataChangeRecord

fn clone(&self) -> DataChangeRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataChangeRecord

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

Formats the value using the given formatter.

impl Default for DataChangeRecord

fn default() -> Self

Returns the “default value” for a type.

impl Message for DataChangeRecord

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 DataChangeRecord

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