Source§fn pre_visit(&mut self, plan: &dyn ExecutionPlan) -> Result<bool, Self::Error>
fn pre_visit(&mut self, plan: &dyn ExecutionPlan) -> Result<bool, Self::Error>
Invoked on an
ExecutionPlan plan before any of its child
inputs have been visited. If Ok(true) is returned, the
recursion continues. If Err(..) or Ok(false) are returned, the
recursion stops immediately and the error, if any, is returned
to acceptSource§fn post_visit(&mut self, _plan: &dyn ExecutionPlan) -> Result<bool, Self::Error>
fn post_visit(&mut self, _plan: &dyn ExecutionPlan) -> Result<bool, Self::Error>
Invoked on an
ExecutionPlan plan after all of its child
inputs have been visited. The return value is handled the same
as the return value of pre_visit. The provided default
implementation returns Ok(true).Source§impl From<PlanComputeVisitor> for ExecutionComputeStats

Source§fn from(value: PlanComputeVisitor) -> Self
fn from(value: PlanComputeVisitor) -> Self
