Struct KeysAndAttributes 

pub struct KeysAndAttributes {
    pub keys: Vec<HashMap<String, AttributeValue>>,

    pub consistent_read: Option<bool>,
    pub attributes_to_get: Vec<String>,
}

A set of keys and optional projection for BatchGetItem.

Describes the items to retrieve from a single table.

Fields

keys: Vec<HashMap<String, AttributeValue>>

consistent_read: Option<bool>

Whether to use a consistent read.

attributes_to_get: Vec<String>

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