Struct aws_sdk_dynamodb::model::ConditionCheck
source · [−]#[non_exhaustive]pub struct ConditionCheck { /* private fields */ }
Expand description
Represents a request to perform a check that an item exists or to check the condition of specific attributes of the item.
Implementations
sourceimpl ConditionCheck
impl ConditionCheck
sourcepub fn key(&self) -> Option<&HashMap<String, AttributeValue>>
pub fn key(&self) -> Option<&HashMap<String, AttributeValue>>
The primary key of the item to be checked. Each element consists of an attribute name and a value for that attribute.
sourcepub fn table_name(&self) -> Option<&str>
pub fn table_name(&self) -> Option<&str>
Name of the table for the check item request.
sourcepub fn condition_expression(&self) -> Option<&str>
pub fn condition_expression(&self) -> Option<&str>
A condition that must be satisfied in order for a conditional update to succeed.
sourcepub fn expression_attribute_names(&self) -> Option<&HashMap<String, String>>
pub fn expression_attribute_names(&self) -> Option<&HashMap<String, String>>
One or more substitution tokens for attribute names in an expression.
sourcepub fn expression_attribute_values(
&self
) -> Option<&HashMap<String, AttributeValue>>
pub fn expression_attribute_values(
&self
) -> Option<&HashMap<String, AttributeValue>>
One or more values that can be substituted in an expression.
sourcepub fn return_values_on_condition_check_failure(
&self
) -> Option<&ReturnValuesOnConditionCheckFailure>
pub fn return_values_on_condition_check_failure(
&self
) -> Option<&ReturnValuesOnConditionCheckFailure>
Use ReturnValuesOnConditionCheckFailure
to get the item attributes if the ConditionCheck
condition fails. For ReturnValuesOnConditionCheckFailure
, the valid values are: NONE and ALL_OLD.
