Expand description

CQL protocol-level representation of a BATCH request, used to execute a batch of statements (prepared, unprepared, or a mix of both).

Fields§

§statements: Cow<'b, [Statement]>

The statements in the batch.

§batch_type: BatchType

The type of the batch.

§consistency: Consistency

The consistency level for the batch.

§serial_consistency: Option<SerialConsistency>

The serial consistency level for the batch, if any.

§timestamp: Option<i64>

The client-side-assigned timestamp for the batch, if any.

§values: Values

The bound values for the batch statements.
