Module value 

JavaScript value representation

The core JsValue type and related structures for representing JavaScript values at runtime.

Structs

Accessor

Accessor functions (getter and/or setter) - boxed to save space for data properties

Binding

Variable binding

BoundFunctionData

Data for a bound function

BytecodeFunction

Bytecode-compiled function

BytecodeGeneratorState

Generator state for bytecode-based generators

EnumData

Enum internal state

EnumMember

Enum member - stores name and value

EnvironmentData

Environment data stored in Environment exotic objects.

GeneratorState

Generator state for suspended generators

Guarded

A JsValue bundled with a Guard that keeps it alive.

GuardedEnv

A guarded environment that keeps itself alive via its guard.

ImportBinding

Reference to a module export for live bindings

JsMapKey

A wrapper around JsValue that implements Hash and Eq using SameValueZero semantics.

JsObject

A JavaScript object

JsString

Reference-counted string for efficient string handling

JsSymbol

JavaScript Symbol primitive Symbols are unique identifiers, optionally with a description

NativeFunction

Native function wrapper

PrivateFieldKey

Key for looking up private fields in an object.

PromiseAllSharedState

Shared state for Promise.all tracking This is shared across all handlers via Rc

PromiseHandler

Handler attached via .then()/.catch()

PromiseRaceSharedState

Shared state for Promise.race tracking First promise to settle wins

PromiseState

Promise internal state

Property

A property descriptor - optimized for size. Most properties are simple data properties, so we optimize for that case.

ProxyData

Proxy internal state

SavedFrameState

Saved frame state for generators This stores the frames and values that need to be restored when resuming

VarKey

A key for variable lookups that uses pointer-based hashing.

Enums

ExoticObject

Exotic object behavior

GeneratorStatus

Status of generator execution

JsFunction

Function representation

JsValue

A JavaScript value

ModuleExport

Represents a module export entry - either a direct export from this module’s environment, or a re-export from another module.

PromiseStatus

Promise status

PropertyKey

Property key (string, index, or symbol)

PropertyStorage

Optimized property storage that uses inline storage for small objects.

PropertyStorageIter

Iterator over PropertyStorage entries.

PropertyStorageIterMut

Mutable iterator over PropertyStorage entries.

Traits

CheapClone

Trait for types that have cheap (O(1), reference-counted) clones.

Functions

create_environment_unrooted

Create a new environment object with its own temporary guard.

create_environment_unrooted_with_capacity

Create a new environment object with pre-allocated capacity for bindings.

create_environment_with_guard

Create a new environment object with a temporary guard.

create_guarded_env

Create a new guarded environment.

number_to_string

Convert a JavaScript number to its canonical string representation.

string_to_number

Convert a JavaScript string to a number according to ECMAScript ToNumber.

Type Aliases

ClassBrandId

Unique identifier for a private field/method.

EnvRef

Environment reference - a GC-managed environment object.

JsObjectRef

Reference to a heap-allocated object (GC-managed)

NativeFn

Native function signature type Returns Guarded to keep newly created objects alive until ownership is transferred.
