Runtime value representation for Meow Meow evaluation.

Variants

Null

Bool(bool)

Number(f64)

Dimension

Numeric value tagged with a source-level unit suffix (e.g. 50%, 20gu, 30deg). Produced by Expression::Dimension. Consumers such as the Style setters use this to disambiguate Percent vs GlyphUnits at the boundary between MMS values and engine types.

Fields

value: f64

unit: Unit

String(String)

Array(Vec<Value>)

Map(HashMap<String, Value>)

ComponentObject

A live engine component (already spawned). Holds the engine-side ComponentId and the MMS component type name (e.g. "Anim", "T"). Produced when let x = CE is evaluated with a live reply channel (eval_with_world). The component_type drives method dispatch.

Fields

id: ComponentId

component_type: String

Object(ObjectId)

Heap-allocated MMS object (map / record / instance).

Identifier(String)

Symbolic identifier value (e.g. enum-like flags passed to constructors).

BuiltinTable(BuiltinTableKind)

Host-provided built-in namespace/table.

ComponentExpr(Box<MaterializedCE>)

A fully-evaluated component expression ready to spawn. Produced whenever a ComponentExpression AST node is evaluated.

Function

A closure: params + body AST + captured environment snapshot.

Fields

params: Vec<String>

body: BlockStatement

captured_env: Arc<HashMap<String, Value>>

heap: HeapHandle

Module

A loaded module: named exports + ordered sequence of root CE emits.

Fields

named: HashMap<String, Value>

sequence: Vec<MaterializedCE>

heap: HeapHandle
