Struct aws_sdk_dynamodb::operation::put_item::PutItemOutput

#[non_exhaustive]
pub struct PutItemOutput {
    pub attributes: Option<HashMap<String, AttributeValue>>,
    pub consumed_capacity: Option<ConsumedCapacity>,
    pub item_collection_metrics: Option<ItemCollectionMetrics>,
    /* private fields */
}

Represents the output of a PutItem 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.

attributes: Option<HashMap<String, AttributeValue>>

The attribute values as they appeared before the PutItem operation, but only if ReturnValues is specified as ALL_OLD in the request. Each element consists of an attribute name and an attribute value.

consumed_capacity: Option<ConsumedCapacity>

The capacity units consumed by the PutItem operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the ReturnConsumedCapacity parameter was specified. For more information, see Capacity unity consumption for write operations in the Amazon DynamoDB Developer Guide.

item_collection_metrics: Option<ItemCollectionMetrics>

Information about item collections, if any, that were affected by the PutItem operation. ItemCollectionMetrics is only returned if the ReturnItemCollectionMetrics parameter was specified. If the table does not have any local secondary indexes, this information is not returned in the response.

Each ItemCollectionMetrics element consists of:

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

• SizeEstimateRangeGB - An estimate of item collection size, in gigabytes. This value 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 that 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.

Implementations

impl PutItemOutput

pub fn attributes(&self) -> Option<&HashMap<String, AttributeValue>>

The attribute values as they appeared before the PutItem operation, but only if ReturnValues is specified as ALL_OLD in the request. Each element consists of an attribute name and an attribute value.

pub fn consumed_capacity(&self) -> Option<&ConsumedCapacity>

The capacity units consumed by the PutItem operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the ReturnConsumedCapacity parameter was specified. For more information, see Capacity unity consumption for write operations in the Amazon DynamoDB Developer Guide.

pub fn item_collection_metrics(&self) -> Option<&ItemCollectionMetrics>

Information about item collections, if any, that were affected by the PutItem operation. ItemCollectionMetrics is only returned if the ReturnItemCollectionMetrics parameter was specified. If the table does not have any local secondary indexes, this information is not returned in the response.

Each ItemCollectionMetrics element consists of:

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

• SizeEstimateRangeGB - An estimate of item collection size, in gigabytes. This value 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 that 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.

impl PutItemOutput

pub fn builder() -> PutItemOutputBuilder

Creates a new builder-style object to manufacture PutItemOutput.

Trait Implementations

impl Clone for PutItemOutput

fn clone(&self) -> PutItemOutput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PutItemOutput

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

Formats the value using the given formatter.

impl PartialEq for PutItemOutput

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

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

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

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

impl RequestId for PutItemOutput

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

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