Struct ExprNode 

pub struct ExprNode {
    pub id: NodeId,
    pub kind: NodeKind,
    pub span: SrcSpan,

Fields

id: NodeId

kind: NodeKind

span: SrcSpan

shape: Option<String>

Symbolic shape text when observed; never invented.

dtype: AbstractDtype

grad: GradState

domain: NumericDomain

Float-range domain after rounding. Unknown until a catalog rule assigns one.

type_name: Option<String>

Best-effort resolved source type. None remains explicitly unknown.
