Expand description

Represents a request to perform an UpdateItem operation.

Implementations

source

impl Update

source

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

The primary key of the item to be updated. Each element consists of an attribute name and a value for that attribute.

source

pub fn update_expression(&self) -> Option<&str>

An expression that defines one or more attributes to be updated, the action to be performed on them, and new value(s) for them.

source

pub fn table_name(&self) -> Option<&str>

Name of the table for the UpdateItem request.

source

pub fn condition_expression(&self) -> Option<&str>

A condition that must be satisfied in order for a conditional update to succeed.

source

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

One or more substitution tokens for attribute names in an expression.

source

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

One or more values that can be substituted in an expression.

source

pub fn return_values_on_condition_check_failure(
&self
) -> Option<&ReturnValuesOnConditionCheckFailure>

Use ReturnValuesOnConditionCheckFailure to get the item attributes if the Update condition fails. For ReturnValuesOnConditionCheckFailure, the valid values are: NONE, ALL_OLD, UPDATED_OLD, ALL_NEW, UPDATED_NEW.

source

impl Update

source

pub fn builder() -> Builder

Creates a new builder-style object to manufacture Update.

Trait Implementations

impl Clone for Update

source

fn clone(&self) -> Update

Returns a copy of the value. Read more
