Function datafusion_physical_expr::aggregate::utils::down_cast_any_ref

pub fn down_cast_any_ref(any: &dyn Any) -> &dyn Any

Downcast a Box<dyn AggregateExpr> or Arc<dyn AggregateExpr> and return the inner trait object as Any so that it can be downcast to a specific implementation.

This method is used when implementing the PartialEq<dyn Any> for AggregateExpr aggregation expressions and allows comparing the equality between the trait objects.
