Struct postgres_parser::sys::AlternativeSubPlan

#[repr(C)]pub struct AlternativeSubPlan {
    pub xpr: Expr,
    pub subplans: *mut List,
}

AlternativeSubPlan expression node for a choice among SubPlans

The subplans are given as a List so that the node definition need not change if there's ever more than two alternatives. For the moment, though, there are always exactly two; and the first one is the faststart plan.

Fields

xpr: Expr

subplans: *mut List
