Struct scylla::transport::execution_profile::ExecutionProfile

pub struct ExecutionProfile(/* private fields */);

A profile that groups configurable options regarding query execution.

Execution profile is immutable as such, but the driver implements double indirection of form: query/Session -> ExecutionProfileHandle -> ExecutionProfile which enables on-fly changing the actual profile associated with all entities (query/Session) by the same handle.

Implementations

impl ExecutionProfile

pub fn builder() -> ExecutionProfileBuilder

Creates a blank builder that can be used to construct new ExecutionProfile.

pub fn to_builder(&self) -> ExecutionProfileBuilder

Creates a builder having all options set to the same as set in this ExecutionProfile.

pub fn into_handle(self) -> ExecutionProfileHandle

Returns a new handle to this ExecutionProfile.

pub fn into_handle_with_label(self, label: String) -> ExecutionProfileHandle

Returns a new handle to this ExecutionProfile, tagging the handle with provided label. The tag, as its name suggests, is only useful for debugging purposes, while being confused about which statement/session is assigned which handle. Identifying handles with tags could then help.

pub fn get_request_timeout(&self) -> Option<Duration>

Gets client timeout associated with this profile.

pub fn get_consistency(&self) -> Consistency

Gets consistency associated with this profile.

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

Gets serial consistency (if set) associated with this profile.

pub fn get_load_balancing_policy(&self) -> &Arc<dyn LoadBalancingPolicy>

Gets load balancing policy associated with this profile.

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

Gets retry policy associated with this profile.

pub fn get_speculative_execution_policy( &self, ) -> Option<&Arc<dyn SpeculativeExecutionPolicy>>

Gets speculative execution policy associated with this profile.
