ResolvedNodeSpec

Struct ResolvedNodeSpec 

Source
pub struct ResolvedNodeSpec {
    pub var: u32,
    pub label_ids: Vec<u32>,
    pub label_names: Vec<String>,
    pub properties: Vec<(String, IrLiteral)>,
    pub computed_properties: Vec<(String, Expr)>,
    pub is_reference: bool,
}
Expand description

A node to create, fully resolved (no expression-arena coupling).

Built by the relational lowering layer from a graphforge_ir::CreateNodeSpec: label IDs are paired with their resolved names and property maps are evaluated to literal key/value pairs, so the execution layer needs no access to the IR arena or ontology.

Fields§

§var: u32

Pattern variable id (VarId.0).

§label_ids: Vec<u32>

Complete resolved label type-id set, in pattern order.

§label_names: Vec<String>

Complete resolved label-name set, in pattern order.

§properties: Vec<(String, IrLiteral)>

Literal property key/value pairs (constant or constant-folded values).

§computed_properties: Vec<(String, Expr)>

Row-dependent property values that could not be folded to a literal (e.g. {n: x} from a driving UNWIND/MATCH): each is a DataFusion Expr over the input columns, evaluated per minted row by the execution layer (#814). Surfaced through the node’s expressions() so the optimizer rewrites the columns they reference.

§is_reference: bool

true when this var was bound by a preceding MATCH/WITH — the executor references the matched node (its identity comes from the input row) rather than minting a new one (#703).
