Variants

Literal(Value)

Env

Fields

name: String

default: Option<NodeId>

Secret

Fields

locator: NodeId

Ref(NodeId)

Ident(String)

Interpolate

Fields

parts: Vec<InterpPart>

Binary

Fields

op: BinOp

lhs: NodeId

rhs: NodeId

Unary

Fields

op: UnOp

expr: NodeId

Array

Fields

elements: Vec<NodeId>

Table

Fields

fields: IndexMap<String, NodeId>

Quantity

Fields

value: NodeId

unit: Unit

ApplyConstraint

Fields

target: NodeId

constraint: Constraint

PatchDirective

A structural patch directive (spec §2.9, C-028): one operation applied to the evaluated value tree after evaluation (and after profile merge), before schema validation. The value expressions are ordinary graph nodes, so patches are dependency-aware.

Fields

op: PatchOp

SchemaField

One field’s schema (spec §2.10, C-030). The constraint arguments are expression nodes evaluated with the document; C-031 reads their values during validation. Edges run argument → field.

Fields

field: SchemaField

SchemaTable

A table of named schemas (spec §2.10). Fields hold SchemaField or nested SchemaTable nodes. Extracted from value fields at parse, so schema tables never export as data.

Fields

fields: IndexMap<String, NodeId>

closed: bool

SchemaArray

An array element schema (spec §2.10): element is a SchemaField node carrying the full element constraints.

Fields

element: NodeId

Semantic

A multi-line string carrying a semantic tag (@prompt, @policy, @template). The tag is tool treatment only — evaluation is transparent to the inner string value (spec §1.4.1).

Fields

tag: SemanticTag

inner: NodeId

Trait Implementations

impl Clone for Node

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Node

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
