expression_attribute_names: Option<HashMap<String, String>>
One or more substitution tokens for attribute names in an expression.
expression_attribute_values: Option<HashMap<String, AttributeValue>>
One or more values that can be substituted in an expression.
key: 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.
return_values_on_condition_check_failure: Option<String>
