Struct PhysicalOrder 

pub struct PhysicalOrder {
    pub position: usize,
    pub descending: bool,
    pub nulls_first: Option<bool>,
    pub nullable: bool,
}

A leading physical row-order property carried between operators.

position is a logical position in the operator’s output schema. Positional tracking keeps duplicate labels and structured qualified identities distinct. nulls_first is irrelevant when nullable is false, which lets a primary-key scan satisfy either explicit NULLS placement without adding a redundant sort.

Fields

position: usize

descending: bool

nulls_first: Option<bool>

nullable: bool
