Struct ItemCollectionMetrics

pub struct ItemCollectionMetrics {
    pub item_collection_key: Option<HashMap<String, AttributeValue>>,
    pub size_estimate_range_gb: Option<Vec<f64>>,
}

Information about item collections, if any, that were affected by the operation. ItemCollectionMetrics is only returned if the request asked for it. If the table does not have any local secondary indexes, this information is not returned in the response.

Fields

item_collection_key: Option<HashMap<String, AttributeValue>>

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

size_estimate_range_gb: Option<Vec<f64>>

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.

Trait Implementations

impl Clone for ItemCollectionMetrics

fn clone(&self) -> ItemCollectionMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemCollectionMetrics

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

Formats the value using the given formatter.

impl Default for ItemCollectionMetrics

fn default() -> ItemCollectionMetrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ItemCollectionMetrics

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ItemCollectionMetrics

fn eq(&self, other: &ItemCollectionMetrics) -> 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.
