#[non_exhaustive]
pub struct UpdateBuilder { /* private fields */ }

A builder for Update.

Implementations

impl UpdateBuilder

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 get_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.

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.

This field is required.

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 get_update_expression(&self) -> &Option<String>

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. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

This field is required.

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

Name of the table for the UpdateItem request. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

pub fn get_table_name(&self) -> &Option<String>

Name of the table for the UpdateItem request. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

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 get_condition_expression(&self) -> &Option<String>

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 get_expression_attribute_names(&self) -> &Option<HashMap<String, String>>

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 get_expression_attribute_values( &self ) -> &Option<HashMap<String, AttributeValue>>

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 and ALL_OLD.

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 and ALL_OLD.

pub fn get_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 and ALL_OLD.

pub fn build(self) -> Result<Update, BuildError>

Consumes the builder and constructs a Update. This method will fail if any of the following fields are not set:

• key
• update_expression
• table_name

Trait Implementations

impl Clone for UpdateBuilder

fn clone(&self) -> UpdateBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateBuilder

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

Formats the value using the given formatter.

impl Default for UpdateBuilder

fn default() -> UpdateBuilder

Returns the “default value” for a type.

impl PartialEq for UpdateBuilder

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

This method tests for self and other values to be equal, and is used by ==.

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

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