EventRecord stores information about each record of a DynamoDb stream event

Fields

aws_region: String

The region in which the GetRecords request was received.

change: StreamRecord

The main body of the stream record, containing all of the DynamoDB-specific fields.

event_id: String

A globally unique identifier for the event that was recorded in this stream record.

event_name: String

The type of data modification that was performed on the DynamoDB table:

• INSERT - a new item was added to the table.

• MODIFY - one or more of an existing item’s attributes were modified.

• REMOVE - the item was deleted from the table

event_source: Option<String>

The AWS service from which the stream record originated. For DynamoDB Streams, this is aws:dynamodb.

event_version: Option<String>

The version number of the stream record format. This number is updated whenever the structure of Record is modified.

Client applications must not assume that eventVersion will remain at a particular value, as this number is subject to change at any time. In general, eventVersion will only increase as the low-level DynamoDB Streams API evolves.

event_source_arn: Option<String>

The event source ARN of DynamoDB

user_identity: Option<UserIdentity>

Items that are deleted by the Time to Live process after expiration have the following fields:

• Records[].userIdentity.type

“Service”

• Records[].userIdentity.principalId

“dynamodb.amazonaws.com”

record_format: Option<String>

Describes the record format and relevant mapping information that should be applied to schematize the records on the stream. For DynamoDB Streams, this is application/json.

table_name: Option<String>

The DynamoDB table that this event was recorded for.

Trait Implementations

impl Clone for EventRecord

fn clone(&self) -> EventRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventRecord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EventRecord

fn eq(&self, other: &EventRecord) -> 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 EventRecord

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
