Struct BatchWriteItemInput

pub struct BatchWriteItemInput {
    pub request_items: HashMap<String, Vec<WriteRequest>>,
    pub return_consumed_capacity: Option<String>,
    pub return_item_collection_metrics: Option<String>,
}

Represents the input of a BatchWriteItem operation.

Fields

request_items: HashMap<String, Vec<WriteRequest>>

A map of one or more table names and, for each table, a list of operations to be performed (DeleteRequest or PutRequest). Each element in the map consists of the following:

• 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. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

• 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 are 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.

return_consumed_capacity: Option<String>

return_item_collection_metrics: Option<String>

Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections, if any, that were modified during the operation are returned in the response. If set to NONE (the default), no statistics are returned.

Trait Implementations

impl Clone for BatchWriteItemInput

fn clone(&self) -> BatchWriteItemInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BatchWriteItemInput

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

Formats the value using the given formatter.

impl Default for BatchWriteItemInput

fn default() -> BatchWriteItemInput

Returns the “default value” for a type.

impl PartialEq for BatchWriteItemInput

fn eq(&self, other: &BatchWriteItemInput) -> 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 Serialize for BatchWriteItemInput

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
