pub fn primitive_recv_kind(node: &AIRNode) -> Option<&str>Expand description
The receiver-kind annotation value, parsed into the primitive type name.
Returns the primitive type’s name (e.g. "Int", "Float", "String") when
the node carries a recv_kind = "Primitive:<Ty>" metadata stamp, else
None. This is the codegen-side reader of the checker→codegen annotation.
