Struct cassandra_cpp::Statement

pub struct Statement(_);

A statement object is an executable query. It represents either a regular (adhoc) statement or a prepared statement. It maintains the queries’ parameter values along with query options (consistency level, paging state, etc.)

Note: Parameters for regular queries are not supported by the binary protocol version 1.

Implementations

impl Statement

pub fn new(query: &str, parameter_count: usize) -> Self

Creates a new query statement.

pub fn add_key_index(&mut self, index: usize) -> Result<&mut Self>

Adds a key index specifier to this a statement. When using token-aware routing, this can be used to tell the driver which parameters within a non-prepared, parameterized statement are part of the partition key.

Use consecutive calls for composite partition keys.

This is not necessary for prepared statements, as the key parameters are determined in the metadata processed in the prepare phase.

pub fn set_keyspace(&mut self, keyspace: String) -> Result<&mut Self>

Sets the statement’s keyspace for use with token-aware routing.

This is not necessary for prepared statements, as the keyspace is determined in the metadata processed in the prepare phase.

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

Sets the statement’s consistency level.

Default: CASS_CONSISTENCY_LOCAL_ONE

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

Sets the statement’s serial consistency level.

Default: Not set

pub fn set_paging_size(&mut self, page_size: i32) -> Result<&mut Self>

Sets the statement’s page size.

Default: -1 (Disabled)

pub fn set_paging_state(&mut self, result: CassResult) -> Result<&mut Self>

Sets the statement’s paging state. This can be used to get the next page of data in a multi-page query.

pub fn set_paging_state_token(&mut self, paging_state: &str) -> Result<&mut Self>

Sets the statement’s paging state. This can be used to get the next page of data in a multi-page query.

Warning: The paging state should not be exposed to or come from untrusted environments. The paging state could be spoofed and potentially used to gain access to other data.

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

Sets the statement’s timestamp.

pub fn set_statement_request_timeout(
    &mut self,
    timeout: Option<Duration>
) -> &mut Self

Sets the statement’s timeout for waiting for a response from a node. Some(Duration::milliseconds(0)) sets no timeout, and None disables it (to use the cluster-level request timeout).

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

Sets the statement’s retry policy.
