}

Analyze and optimize a logical plan using metadata captured for this call.

Required Methods

fn plan_for_execution( &self, plan: UnifiedPlan, params: &[SQLParam], ) -> Result<UnifiedPlan, SQLError>

fn plan_with_result( &self, plan: UnifiedPlan, params: &[SQLParam], ) -> Result<(UnifiedPlan, AnalyzedResult), SQLError>

Analyze and optimize a logical plan, and return what its analysis derives about its result.

Provided Methods

fn plan_with_cached_analysis( &self, plan: UnifiedPlan, params: &[SQLParam], _cached: Option<Arc<AnalyzedStatement>>, ) -> Result<(UnifiedPlan, Option<Arc<AnalyzedStatement>>), SQLError>

Reuse analysis only after the caller validates its catalog/scope in the selected snapshot. Optimization still runs for this invocation. The default retains full analysis for implementations without this capability.

fn plan_for_statement_cache( &self, plan: UnifiedPlan, params: &[SQLParam], ) -> Result<(UnifiedPlan, bool), SQLError>

Return an executable and whether its analysis inputs permit reuse across ordinary messages. Planners without that evidence must analyze again.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
