Trait ExecutablePlanOptimizer 

pub trait ExecutablePlanOptimizer {
    // 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>;

    // Provided method
    fn plan_for_statement_cache(
        &self,
        plan: UnifiedPlan,
        params: &[SQLParam],
    ) -> Result<(UnifiedPlan, bool), SQLError> { ... }
}

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_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".
