Input for the GetItem operation.

Fields

table_name: String

The name of the table containing the item.

key: HashMap<String, AttributeValue>

A map of attribute names to AttributeValue objects representing the primary key of the item to retrieve.

consistent_read: Option<bool>

If true, a strongly consistent read is used; otherwise, an eventually consistent read is used.

projection_expression: Option<String>

A string that identifies the attributes to retrieve from the table.

expression_attribute_names: HashMap<String, String>

Substitution tokens for attribute names in an expression.

return_consumed_capacity: Option<ReturnConsumedCapacity>

Determines the level of detail about provisioned throughput consumption.

attributes_to_get: Option<Vec<String>>

Legacy: attribute names to retrieve (use projection_expression instead).
