sourcepub fn items(self, input: HashMap<String, AttributeValue>) -> Self
pub fn items(self, input: HashMap<String, AttributeValue>) -> Self
Appends an item to items.
To override the contents of this collection use set_items.
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.
sourcepub fn set_items(
self,
input: Option<Vec<HashMap<String, AttributeValue>>>

pub fn set_items(
self,
input: Option<Vec<HashMap<String, AttributeValue>>>
) -> Self
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.

If you did not use a filter in the request, then Count and ScannedCount are the same.

pub fn scanned_count(self, input: i32) -> Self
The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.
If you did not use a filter in the request, then ScannedCount is the same as Count.

}sourcepub fn last_evaluated_key(self, k: impl Into<String>, v: AttributeValue) -> Self
pub fn last_evaluated_key(self, k: impl Into<String>, v: AttributeValue) -> Self
Adds a key-value pair to last_evaluated_key.
To override the contents of this collection use set_last_evaluated_key.
The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.
If LastEvaluatedKey is empty, then the "last page" of results has been processed and there is no more data to be retrieved.
If LastEvaluatedKey is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is empty.
