Struct aws_sdk_dynamodb::types::ParameterizedStatement

#[non_exhaustive]
pub struct ParameterizedStatement {
    pub statement: String,
    pub parameters: Option<Vec<AttributeValue>>,
    pub return_values_on_condition_check_failure: Option<ReturnValuesOnConditionCheckFailure>,
}

Represents a PartiQL statement that uses parameters.

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: String

A PartiQL statement that uses parameters.

parameters: Option<Vec<AttributeValue>>

The parameter values.

return_values_on_condition_check_failure: Option<ReturnValuesOnConditionCheckFailure>

An optional parameter that returns the item attributes for a PartiQL ParameterizedStatement 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 ParameterizedStatement

pub fn statement(&self) -> &str

A PartiQL statement that uses parameters.

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

The parameter values.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .parameters.is_none().

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

An optional parameter that returns the item attributes for a PartiQL ParameterizedStatement 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 ParameterizedStatement

pub fn builder() -> ParameterizedStatementBuilder

Creates a new builder-style object to manufacture ParameterizedStatement.

Trait Implementations

impl Clone for ParameterizedStatement

fn clone(&self) -> ParameterizedStatement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterizedStatement

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

Formats the value using the given formatter.

impl PartialEq for ParameterizedStatement

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