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>,
    /* private fields */
}

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>

ALL_OLD hands back the item this member’s UPDATE or DELETE failed its condition on, on the member’s Error; NONE, or leaving it out, does not (captured eu-west-2 and us-east-1, 2026-10-10, which corrects a 2026-08-15 measurement that found no item either way).
