A builder for PutItemInput

Implementations

impl Builder

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

The name of the table to contain the item.

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

The name of the table to contain the item.

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

Adds a key-value pair to item.

To override the contents of this collection use set_item.

A map of attribute name/value pairs, one for each attribute. Only the primary key attributes are required; you can optionally provide other attribute name-value pairs for the item.

You must provide all of the attributes for the primary key. 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 both values for both the partition key and the sort key.

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.

Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a length greater than zero if the attribute is used as a key attribute for a table or index.

For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide.

Each element in the Item map is an AttributeValue object.

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

A map of attribute name/value pairs, one for each attribute. Only the primary key attributes are required; you can optionally provide other attribute name-value pairs for the item.

You must provide all of the attributes for the primary key. 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 both values for both the partition key and the sort key.

Each element in the Item map is an AttributeValue object.

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

Adds a key-value pair to expected.

To override the contents of this collection use set_expected.

This is a legacy parameter. Use ConditionExpression instead. For more information, see Expected in the Amazon DynamoDB Developer Guide.

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

This is a legacy parameter. Use ConditionExpression instead. For more information, see Expected in the Amazon DynamoDB Developer Guide.

pub fn return_values(self, input: ReturnValue) -> Self

Use ReturnValues if you want to get the item attributes as they appeared before they were updated with the PutItem request. For PutItem, the valid values are:

• NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)

• ALL_OLD - If PutItem overwrote an attribute name-value pair, then the content of the old item is returned.

The values returned are strongly consistent.

The ReturnValues parameter is used by several DynamoDB operations; however, PutItem does not recognize any values other than NONE or ALL_OLD.

pub fn set_return_values(self, input: Option<ReturnValue>) -> Self

Use ReturnValues if you want to get the item attributes as they appeared before they were updated with the PutItem request. For PutItem, the valid values are:

• NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)

• ALL_OLD - If PutItem overwrote an attribute name-value pair, then the content of the old item is returned.

The values returned are strongly consistent.

The ReturnValues parameter is used by several DynamoDB operations; however, PutItem does not recognize any values other than NONE or ALL_OLD.

pub fn return_consumed_capacity(self, input: ReturnConsumedCapacity) -> Self

Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:

• INDEXES - The response includes the aggregate ConsumedCapacity for the operation, together with ConsumedCapacity for each table and secondary index that was accessed.

  Note that some operations, such as GetItem and BatchGetItem, do not access any indexes at all. In these cases, specifying INDEXES will only return ConsumedCapacity information for table(s).

• TOTAL - The response includes only the aggregate ConsumedCapacity for the operation.

• NONE - No ConsumedCapacity details are included in the response.

pub fn set_return_consumed_capacity(
    self,
    input: Option<ReturnConsumedCapacity>
) -> Self

Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:

• INDEXES - The response includes the aggregate ConsumedCapacity for the operation, together with ConsumedCapacity for each table and secondary index that was accessed.

  Note that some operations, such as GetItem and BatchGetItem, do not access any indexes at all. In these cases, specifying INDEXES will only return ConsumedCapacity information for table(s).

• TOTAL - The response includes only the aggregate ConsumedCapacity for the operation.

• NONE - No ConsumedCapacity details are included in the response.

pub fn return_item_collection_metrics(
    self,
    input: ReturnItemCollectionMetrics
) -> Self

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.

pub fn set_return_item_collection_metrics(
    self,
    input: Option<ReturnItemCollectionMetrics>
) -> Self

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.

pub fn conditional_operator(self, input: ConditionalOperator) -> Self

This is a legacy parameter. Use ConditionExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.

pub fn set_conditional_operator(
    self,
    input: Option<ConditionalOperator>
) -> Self

This is a legacy parameter. Use ConditionExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.

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

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

An expression can contain any of the following:

• Functions: attribute_exists | attribute_not_exists | attribute_type | contains | begins_with | size

  These function names are case-sensitive.

• Comparison operators: = | <> | < | > | <= | >= | BETWEEN | IN

• Logical operators: AND | OR | NOT

For more information on condition expressions, see Condition Expressions in the Amazon DynamoDB Developer Guide.

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

An expression can contain any of the following:

• Functions: attribute_exists | attribute_not_exists | attribute_type | contains | begins_with | size

  These function names are case-sensitive.

• Comparison operators: = | <> | < | > | <= | >= | BETWEEN | IN

• Logical operators: AND | OR | NOT

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. The following are some use cases for using ExpressionAttributeNames:

• To access an attribute whose name conflicts with a DynamoDB reserved word.

• To create a placeholder for repeating occurrences of an attribute name in an expression.

• To prevent special characters in an attribute name from being misinterpreted in an expression.

Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

• Percentile

The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

• {"#P":"Percentile"}

You could then use this substitution in an expression, as in this example:

• #P = :val

Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

For more information on expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

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

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.

Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the ProductStatus attribute was one of the following:

Available | Backordered | Discontinued

You would first need to specify ExpressionAttributeValues as follows:

{ ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

You could then use these values in an expression, such as this:

ProductStatus IN (:avail, :back, :disc)

For more information on expression attribute values, see Condition Expressions in the Amazon DynamoDB Developer Guide.

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