Struct FetchRequest 

pub struct FetchRequest {
    pub constraint: Option<Constraint>,
    pub multi_constraints: Vec<MultiConstraint>,
    pub start: Option<Start>,
    pub reverse: bool,
}

What Input::fetch receives. multi_constraints (from FlippedJoin) is a disjunction-of-conjunctions IN-batch; empty ⇒ the single-constraint path.

Fields

constraint: Option<Constraint>

multi_constraints: Vec<MultiConstraint>

start: Option<Start>

reverse: bool

Implementations

impl FetchRequest

pub fn all() -> FetchRequest

pub fn with_constraint(c: Constraint) -> FetchRequest

pub fn has_multi(&self) -> bool

Mirrors the #fetch guard: multiConstraints?.some(mc => mc.length > 0) (memory-source.ts:264). Empty entries don’t count.
