Represents the output of a BatchWriteItem operation.

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.

unprocessed_items: Option<HashMap<String, Vec<WriteRequest>>>

A map of tables and requests against those tables that were not processed. The UnprocessedItems value is in the same form as RequestItems, so you can provide this value directly to a subsequent BatchWriteItem operation. For more information, see RequestItems in the Request Parameters section.

Each UnprocessedItems entry consists of a table name or table ARN and, for that table, a list of operations to perform (DeleteRequest or PutRequest).

• DeleteRequest - Perform a DeleteItem operation on the specified item. The item to be deleted is identified by a Key subelement:

  • Key - A map of primary key attribute values that uniquely identify the item. Each entry in this map consists of an attribute name and an attribute value.

• PutRequest - Perform a PutItem operation on the specified item. The item to be put is identified by an Item subelement:

  • Item - A map of attributes and their values. Each entry in this map consists of an attribute name and an attribute value. Attribute values must not be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests that contain empty values will be rejected with a ValidationException exception.

    If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

If there are no unprocessed items remaining, the response contains an empty UnprocessedItems map.

item_collection_metrics: Option<HashMap<String, Vec<ItemCollectionMetrics>>>

A list of tables that were processed by BatchWriteItem and, for each table, information about any item collections that were affected by individual DeleteItem or PutItem operations.

Each entry consists of the following subelements:

• ItemCollectionKey - The partition key value of the item collection. This is the same as the partition key value of the item.

• SizeEstimateRangeGB - An estimate of item collection size, expressed in GB. This is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on the table. Use this estimate to measure whether a local secondary index is approaching its size limit.

  The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.

consumed_capacity: Option<Vec<ConsumedCapacity>>

The capacity units consumed by the entire BatchWriteItem operation.

Each element consists of:

• TableName - The table that consumed the provisioned throughput.

• CapacityUnits - The total number of capacity units consumed.

Implementations

impl BatchWriteItemOutput

pub fn unprocessed_items(&self) -> Option<&HashMap<String, Vec<WriteRequest>>>

A map of tables and requests against those tables that were not processed. The UnprocessedItems value is in the same form as RequestItems, so you can provide this value directly to a subsequent BatchWriteItem operation. For more information, see RequestItems in the Request Parameters section.

pub fn item_collection_metrics( &self, ) -> Option<&HashMap<String, Vec<ItemCollectionMetrics>>>

A list of tables that were processed by BatchWriteItem and, for each table, information about any item collections that were affected by individual DeleteItem or PutItem operations.

Each entry consists of the following subelements:

• ItemCollectionKey - The partition key value of the item collection. This is the same as the partition key value of the item.

• SizeEstimateRangeGB - An estimate of item collection size, expressed in GB. This is a two-element array containing a lower bound and an upper bound for the estimate.

Use this estimate to measure whether a local secondary index is approaching its size limit.

  The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.

pub fn consumed_capacity(&self) -> &[ConsumedCapacity]

The capacity units consumed by the entire BatchWriteItem operation.

Each element consists of:

• TableName - The table that consumed the provisioned throughput.

• CapacityUnits - The total number of capacity units consumed.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .consumed_capacity.is_none().

impl BatchWriteItemOutput

pub fn builder() -> BatchWriteItemOutputBuilder

Creates a new builder-style object to manufacture BatchWriteItemOutput.

Trait Implementations

impl Clone for BatchWriteItemOutput

fn clone(&self) -> BatchWriteItemOutput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BatchWriteItemOutput

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

Formats the value using the given formatter.

impl PartialEq for BatchWriteItemOutput

fn eq(&self, other: &BatchWriteItemOutput) -> 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 RequestId for BatchWriteItemOutput

fn request_id(&self) -> Option<&str>

Returns the request ID, or None if the service could not be reached.
