Struct PushedDownPredicate 

pub struct PushedDownPredicate {
    pub discriminant: PushedDown,
    pub predicate: Arc<dyn PhysicalExpr>,
}

The result of a plan for pushing down a filter into a child node. This contains references to filters so that nodes can mutate a filter before pushing it down to a child node (e.g. to adjust a projection) or can directly take ownership of filters that their children could not handle.

Fields

discriminant: PushedDown

predicate: Arc<dyn PhysicalExpr>

Implementations

pub fn supported(predicate: Arc<dyn PhysicalExpr>) -> Self

Create a new PushedDownPredicate with supported pushdown.

pub fn unsupported(predicate: Arc<dyn PhysicalExpr>) -> Self

Create a new PushedDownPredicate with unsupported pushdown.
