Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

statement: Option<String>

The PartiQL statement representing the operation to run.

parameters: Option<Vec<AttributeValue>>

The parameters for the PartiQL statement, if any.

consistent_read: Option<bool>

The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.

next_token: Option<String>

Set this value to get remaining results, if NextToken was returned in the statement response.

return_consumed_capacity: Option<ReturnConsumedCapacity>

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.

limit: Option<i32>

The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, along with a key in LastEvaluatedKey to apply in a subsequent operation so you can pick up where you left off. Also, if the processed dataset size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation.

return_values_on_condition_check_failure: Option<ReturnValuesOnConditionCheckFailure>

An optional parameter that returns the item attributes for an ExecuteStatement operation that failed a condition check.

There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

Implementations

impl ExecuteStatementInput

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

The PartiQL statement representing the operation to run.

pub fn parameters(&self) -> Option<&[AttributeValue]>

The parameters for the PartiQL statement, if any.

pub fn consistent_read(&self) -> Option<bool>

The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.

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

Set this value to get remaining results, if NextToken was returned in the statement response.

pub fn return_consumed_capacity(&self) -> Option<&ReturnConsumedCapacity>

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 limit(&self) -> Option<i32>

The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, along with a key in LastEvaluatedKey to apply in a subsequent operation so you can pick up where you left off. Also, if the processed dataset size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation.

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

An optional parameter that returns the item attributes for an ExecuteStatement operation that failed a condition check.

There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

impl ExecuteStatementInput

pub fn builder() -> ExecuteStatementInputBuilder

Creates a new builder-style object to manufacture ExecuteStatementInput.

Trait Implementations

impl Clone for ExecuteStatementInput

fn clone(&self) -> ExecuteStatementInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecuteStatementInput

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

Formats the value using the given formatter.

impl PartialEq<ExecuteStatementInput> for ExecuteStatementInput

fn eq(&self, other: &ExecuteStatementInput) -> 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.
