Fields

account_id: String

region: String

tables: BTreeMap<String, DynamoTable>

backups: BTreeMap<String, BackupDescription>

global_tables: BTreeMap<String, GlobalTableDescription>

exports: BTreeMap<String, ExportDescription>

imports: BTreeMap<String, ImportDescription>

lambda_stream_checkpoints: BTreeMap<String, String>

DynamoDB Streams -> Lambda event-source-mapping checkpoints: the last stream sequence number delivered for each mapping (keyed by ESM uuid). Persisted so the streams poller resumes from where it left off after a restart instead of re-seeding TRIM_HORIZON and re-invoking the target Lambda with the whole retained backlog (duplicate side effects). Mirrors KinesisState.lambda_checkpoints. #[serde(default)] keeps older snapshots loadable.

Implementations

impl DynamoDbState

pub fn new(account_id: &str, region: &str) -> Self

pub fn reset(&mut self)

pub fn lambda_stream_checkpoint(&self, mapping_uuid: &str) -> Option<String>

Last stream sequence number delivered for the given DynamoDB Streams -> Lambda event source mapping, or None if the mapping has never delivered (so the poller seeds from StartingPosition).

pub fn set_lambda_stream_checkpoint( &mut self, mapping_uuid: &str, sequence_number: String, )

Record the last stream sequence number delivered for a mapping. The value rides along with the next DynamoDB snapshot save, exactly the way Kinesis lambda checkpoints persist through their snapshot.

Trait Implementations

impl AccountState for DynamoDbState

fn new_for_account(account_id: &str, region: &str, _endpoint: &str) -> Self

Create a fresh, empty state for the given account.

fn inherit_from(&mut self, _sibling: &Self)

Called after a new account state is created via MultiAccountState::get_or_create, with a reference to an existing sibling state. Services can override this to propagate shared resources (e.g. body caches) to the new state.

impl Clone for DynamoDbState

fn clone(&self) -> DynamoDbState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamoDbState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DynamoDbState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DynamoDbState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
