A heap object.

Variants

Str(String)

Array(Vec<Value>)

Object(IndexMap<String, Value>)

Func(FuncVal)

Builtin(String)

A first-class reference to a builtin function or namespace (console.log, Math, parseInt).

BoundMethod

A bound method value (obj.method captured then called): dispatches through call_method(recv, name, args) when invoked.

Fields

recv: Value

name: String

Null

The single canonical null.

Iter

A live iterator over a sequence, with a cursor.

Fields

items: Vec<Value>

idx: usize

BoundFunc

A bound function (fn.bind(thisArg, ...preargs)).

Fields

target: Value

this: Value

args: Vec<Value>

Class(ClassVal)

A class constructor value: the runtime object produced by a class.

Symbol

A Symbol — a unique property key. registered marks a Symbol.for key (shared) vs a fresh Symbol().

Fields

desc: Option<String>

id: u64

Map

A Map (or WeakMap when weak): insertion-ordered key→value entries.

Fields

entries: IndexMap<MapKey, (Value, Value)>

weak: bool

Set

A Set (or WeakSet when weak): insertion-ordered unique values.

Fields

entries: IndexMap<MapKey, Value>

weak: bool

Generator

A live generator, backed by a stackful corosensei coroutine in JsHost.generators.

Fields

id: u32

Promise

A Promise, backed by a PromiseCell in JsHost.promises.

Fields

id: u32

BigInt(BigInt)

An arbitrary-precision BigInt (typeof === "bigint").

RegExp(Box<RegExpObj>)

A compiled regular expression (/pat/flags or new RegExp(...)).

Proxy

A Proxy: every essential internal method is diverted to handler’s traps (see crate::proxy). revoked is set by the thunk Proxy.revocable hands back, after which every operation throws.

Fields

target: Value

handler: Value

revoked: bool

Implementations

impl JsObj

pub fn kind(&self) -> ObjKind

This object’s variant, without touching its contents.

Trait Implementations

impl Clone for JsObj

fn clone(&self) -> JsObj

Returns a duplicate of the value.

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

Performs copy-assignment from source.
