Implementations

impl Builder

pub fn key(self, k: impl Into<String>, v: AttributeValue) -> Self

Adds a key-value pair to key.

To override the contents of this collection use set_key.

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

pub fn set_key(self, input: Option<HashMap<String, AttributeValue>>) -> Self

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

pub fn update_expression(self, input: impl Into<String>) -> Self

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

pub fn set_update_expression(self, input: Option<String>) -> Self

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

pub fn table_name(self, input: impl Into<String>) -> Self

Name of the table for the UpdateItem request.

pub fn set_table_name(self, input: Option<String>) -> Self

Name of the table for the UpdateItem request.

pub fn condition_expression(self, input: impl Into<String>) -> Self

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

pub fn set_condition_expression(self, input: Option<String>) -> Self

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

pub fn expression_attribute_names(
    self,
    k: impl Into<String>,
    v: impl Into<String>
) -> Self

Adds a key-value pair to expression_attribute_names.

To override the contents of this collection use set_expression_attribute_names.

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

pub fn set_expression_attribute_names(
    self,
    input: Option<HashMap<String, String>>
) -> Self

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

pub fn expression_attribute_values(
    self,
    k: impl Into<String>,
    v: AttributeValue
) -> Self

Adds a key-value pair to expression_attribute_values.

To override the contents of this collection use set_expression_attribute_values.

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

pub fn set_expression_attribute_values(
    self,
    input: Option<HashMap<String, AttributeValue>>
) -> Self

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

pub fn return_values_on_condition_check_failure(
    self,
    input: ReturnValuesOnConditionCheckFailure
) -> Self

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.

pub fn set_return_values_on_condition_check_failure(
    self,
    input: Option<ReturnValuesOnConditionCheckFailure>
) -> Self

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.

pub fn build(self) -> Update

Consumes the builder and constructs a Update
