Struct Batch

pub struct Batch<T = Bound>(/* private fields */);

A group of statements that are executed as a single batch. Note: Batches are not supported by the binary protocol version 1.

Implementations

impl<T> Batch<T>

pub fn session(&self) -> &Session<T>

Returns the session of which this batch is bound to.

pub async fn execute(self) -> Result<CassResult>

Executes this batch.

pub fn set_consistency(&mut self, consistency: Consistency) -> Result<&mut Self>

Sets the batch’s consistency level

pub fn set_serial_consistency( &mut self, consistency: Consistency, ) -> Result<&mut Self>

Sets the batch’s serial consistency level.

Default: Not set

pub fn set_timestamp(&mut self, timestamp: i64) -> Result<&mut Self>

Sets the batch’s timestamp.

pub fn set_retry_policy( &mut self, retry_policy: RetryPolicy, ) -> Result<&mut Self>

Sets the batch’s retry policy.

pub fn set_custom_payload( &mut self, custom_payload: CustomPayload, ) -> Result<&mut Self>

Sets the batch’s custom payload.

pub fn add_statement(&mut self, statement: Statement<T>) -> Result<&mut Self>

Adds a statement to a batch.

pub fn set_is_idempotent(&mut self, is_idempotent: bool) -> Result<&mut Self>

Sets whether the statements in a batch are idempotent. Idempotent batches are able to be automatically retried after timeouts/errors and can be speculatively executed.

fn fmt(&self, f: &mut Formatter<'_>) -> Result
