Struct dynamo_subscriber::types::Shard

pub struct Shard { /* private fields */ }

A shard representation to retreive DynamoDB Streams records.

Implementations

impl Shard

pub fn new(shard: Shard) -> Option<Self>

Create a new shard from aws_sdk_dynamodbstreams::types::Shard. If the input’s shard_id is None, this method also returns None.

use aws_sdk_dynamodbstreams as dynamodbstreams;
use dynamo_subscriber::types::Shard;

// Create a aws_sdk_dynamodbstreams's Shard with shard_id
let original = dynamodbstreams::types::Shard::builder()
    .shard_id("0001")
    .build();
assert!(original.shard_id().is_some());

// This case, the shard should exist.
let shard = Shard::new(original);
assert!(shard.is_some());

// Create a aws_sdk_dynamodbstreams's Shard without shard_id
let original = dynamodbstreams::types::Shard::builder()
    .build();
assert!(original.shard_id().is_none());

// This case, the shard should not exist.
let shard = Shard::new(original);
assert!(shard.is_none());

pub fn id(&self) -> &str

Return the shard id.

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

Return the shard iterator id.

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

Return the parent shard id.

pub fn set_iterator(self, iterator: Option<String>) -> Self

Return Shard with passed shard iterator id.
