Trait datafusion::optimizer::optimizer::OptimizerRule [−][src]
pub trait OptimizerRule {
fn optimize(&self, plan: &LogicalPlan) -> Result<LogicalPlan>;
fn name(&self) -> &str;
}OptimizerRule transforms one [‘LogicalPlan’] into another which
computes the same results, but in a potentially more efficient
way.
Required methods
fn optimize(&self, plan: &LogicalPlan) -> Result<LogicalPlan>[src]
Rewrite plan to an optimized form
fn name(&self) -> &str[src]
A human readable name for this optimizer rule
