rdf_fusion::logical::extend

Struct ExtendLoweringRule

pub struct ExtendLoweringRule;

Expand description

An optimizer rule that lowers an ExtendNode into a projection.

Implementations§

impl ExtendLoweringRule

pub fn new() -> ExtendLoweringRule

Creates a new ExtendLoweringRule.

Trait Implementations§

impl Debug for ExtendLoweringRule

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

Formats the value using the given formatter. Read more

impl Default for ExtendLoweringRule

fn default() -> ExtendLoweringRule

Returns the “default value” for a type. Read more

impl OptimizerRule for ExtendLoweringRule

fn name(&self) -> &str

A human readable name for this optimizer rule

fn rewrite( &self, plan: LogicalPlan, _config: &dyn OptimizerConfig, ) -> Result<Transformed<LogicalPlan>, DataFusionError>

Try to rewrite plan to an optimized form, returning Transformed::yes if the plan was rewritten and Transformed::no if it was not.

fn apply_order(&self) -> Option<ApplyOrder>

How should the rule be applied by the optimizer? See comments on ApplyOrder for details. Read more

fn supports_rewrite(&self) -> bool

👎Deprecated since 47.0.0: This method is no longer used

Does this rule support rewriting owned plans (rather than by reference)?
