Implementations§

impl DecorrelateLateralJoin

pub fn new() -> Self

Trait Implementations§

impl Debug for DecorrelateLateralJoin

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

Formats the value using the given formatter. Read more

impl Default for DecorrelateLateralJoin

fn default() -> DecorrelateLateralJoin

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

impl OptimizerRule for DecorrelateLateralJoin

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)?

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

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

fn name(&self) -> &str

A human readable name for this optimizer rule

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

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