Struct Record

#[non_exhaustive]
pub struct Record {
    pub event_id: Option<String>,
    pub event_name: Option<OperationType>,
    pub event_version: Option<String>,
    pub event_source: Option<String>,
    pub aws_region: Option<String>,
    pub dynamodb: Option<StreamRecord>,
    pub user_identity: Option<Identity>,
}

A description of a unique event within a stream.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

event_id: Option<String>

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

event_name: Option<OperationType>

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_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: Option<String>

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

aws_region: Option<String>

The region in which the GetRecords request was received.

dynamodb: Option<StreamRecord>

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

user_identity: Option<Identity>

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"

Implementations

impl Record

pub fn event_id(&self) -> Option<&str>

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

pub fn event_name(&self) -> Option<&OperationType>

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

pub fn event_version(&self) -> Option<&str>

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.

pub fn event_source(&self) -> Option<&str>

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

pub fn aws_region(&self) -> Option<&str>

The region in which the GetRecords request was received.

pub fn dynamodb(&self) -> Option<&StreamRecord>

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

pub fn user_identity(&self) -> Option<&Identity>

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"

impl Record

pub fn builder() -> RecordBuilder

Creates a new builder-style object to manufacture Record.

Trait Implementations

impl Clone for Record

fn clone(&self) -> Record

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Record

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

Formats the value using the given formatter.

impl PartialEq for Record

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

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

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

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