Struct ForeignPhysicalOptimizerRule 

pub struct ForeignPhysicalOptimizerRule { /* private fields */ }

This wrapper struct exists on the receiver side of the FFI interface, so it has no guarantees about being able to access the data in private_data. Any functions defined on this struct must only use the stable functions provided in FFI_PhysicalOptimizerRule to interact with the foreign rule.

Trait Implementations

impl Debug for ForeignPhysicalOptimizerRule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PhysicalOptimizerRule for ForeignPhysicalOptimizerRule

fn optimize( &self, plan: Arc<dyn ExecutionPlan>, config: &ConfigOptions, ) -> Result<Arc<dyn ExecutionPlan>>

Rewrite plan to an optimized form.

fn name(&self) -> &str

A human readable name for this optimizer rule

fn schema_check(&self) -> bool

A flag to indicate whether the physical planner should validate that the rule will not change the schema of the plan after the rewriting. Some of the optimization rules might change the nullable properties of the schema and should disable the schema check.

fn optimize_with_context( &self, plan: Arc<dyn ExecutionPlan>, context: &dyn PhysicalOptimizerContext, ) -> Result<Arc<dyn ExecutionPlan>, DataFusionError>

Rewrite plan with access to extended context (statistics registry, etc.).
