Struct SetTarget 

pub struct SetTarget {
    pub var: u32,
    pub is_edge: bool,
    pub prop_name: String,
    pub value: Expr,
}

One resolved SET n.prop = <expr> target (#791).

Like DeleteTarget, the node/edge kind (is_edge) is resolved by the lowering layer from the input schema. value is the lowered DataFusion expression for the assigned value — evaluated per matched row at execution time (mirrors how UnwindNode carries its list_expr).

The property-file stem is resolved per row in the exec layer, not baked here: a node uses its type_id (→ _untyped in Exploratory mode, else the entity name from GraphSetNode::type_id_to_entity_name); an edge uses its rel_type_name column (edge property files are keyed by relation name in every mode).

Fields

var: u32

Pattern variable id (VarId.0).

is_edge: bool

true if the variable is an edge (write to edge_properties/); false for a node (write to properties/).

prop_name: String

The property name being assigned.

value: Expr

The value expression, evaluated per matched row in the exec layer.
