Struct BatchStatementRequest 

#[non_exhaustive]
pub struct BatchStatementRequest {
    pub statement: String,
    pub parameters: Option<Vec<AttributeValue>>,
    pub consistent_read: Option<bool>,
    pub return_values_on_condition_check_failure: Option<String>,
}

One member of a batch.

#[non_exhaustive] because DynamoDB grows this shape and has already grown it twice here: ConsistentRead and ReturnValuesOnConditionCheckFailure both arrived after the type was first written. The attribute means the next one costs consumers nothing. Construct one from Default and assign, or deserialise it. The enclosing BatchExecuteStatementRequest is deliberately not marked: it carries Statements and ReturnConsumedCapacity, which is the whole of DynamoDB’s shape.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

statement: String

parameters: Option<Vec<AttributeValue>>

consistent_read: Option<bool>

Per member, not per batch. Does not change which rows come back, because every read against SQLite is already strongly consistent, but it does change the rate the read is charged at: a keyed batch SELECT costs 0.5 without it and 1 with it, and a batch mixing the two sums both rates.

return_values_on_condition_check_failure: Option<String>

Accepted and inert, which is what DynamoDB does with it. A batch member whose condition fails returns the same response whether this is ALL_OLD, NONE, or absent, and never carries the item: measured against a TransactWriteItems ConditionCheck in the same round, which does return it. The field is deserialised so a client setting it meets a field dynoxide knows rather than one it drops.
