pub struct PreparedStatement {
    pub prepare_tracing_ids: Vec<Uuid>,
    // some fields omitted
}

Represents a statement prepared on the server.

prepare_tracing_ids: Vec<Uuid>

Implementations

impl PreparedStatement

pub fn new(
    id: Bytes,
    metadata: PreparedMetadata,
    statement: String,
    page_size: Option<i32>
) -> Self

pub fn get_id(&self) -> &Bytes

pub fn get_statement(&self) -> &str

pub fn set_page_size(&mut self, page_size: i32)

Sets the page size for this CQL query.

pub fn disable_paging(&mut self)

Disables paging for this CQL query.

pub fn get_page_size(&self) -> Option<i32>

Returns the page size for this CQL query.

pub fn get_prepare_tracing_ids(&self) -> &[Uuid]

Gets tracing ids of queries used to prepare this statement

pub fn compute_partition_key(
    &self,
    bound_values: &SerializedValues
) -> Result<Bytes, PartitionKeyError>

Computes the partition key of the target table from given values Partition keys have a specific serialization rules. Ref: https://github.com/scylladb/scylla/blob/40adf38915b6d8f5314c621a94d694d172360833/compound_compat.hh#L33-L47

pub fn get_keyspace_name(&self) -> Option<&str>

Returns the name of the keyspace this statement is operating on.

pub fn set_consistency(&mut self, c: Consistency)

Sets the consistency to be used when executing this batch.

pub fn get_consistency(&self) -> Consistency

Gets the consistency to be used when executing this batch.

pub fn set_serial_consistency(&mut self, sc: Option<Consistency>)

Sets the serial consistency to be used when executing this batch. (Ignored unless the batch is an LWT)

pub fn get_serial_consistency(&self) -> Option<Consistency>

Gets the serial consistency to be used when executing this batch. (Ignored unless the batch is an LWT)

pub fn set_is_idempotent(&mut self, is_idempotent: bool)

Sets the idempotence of this statement A query is idempotent if it can be applied multiple times without changing the result of the initial application If set to true we can be sure that it is idempotent If set to false it is unknown whether it is idempotent This is used in RetryPolicy to decide if retrying a query is safe

pub fn get_is_idempotent(&self) -> bool

Gets the idempotence of this statement

pub fn set_retry_policy(&mut self, retry_policy: Box<dyn RetryPolicy>)

Sets a custom RetryPolicy to be used with this statement By default Session’s retry policy is used, this allows to use a custom retry policy

pub fn get_retry_policy(&self) -> &Option<Box<dyn RetryPolicy>>

Gets custom RetryPolicy used by this statement

pub fn set_tracing(&mut self, should_trace: bool)

Enable or disable CQL Tracing for this batch If enabled session.batch() will return a BatchResult containing tracing_id which can be used to query tracing information about the execution of this query

pub fn get_tracing(&self) -> bool

Gets whether tracing is enabled for this batch

Trait Implementations

impl Clone for PreparedStatement

fn clone(&self) -> PreparedStatement

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<PreparedStatement> for BatchStatement

fn from(p: PreparedStatement) -> Self

Performs the conversion.
