Module builtins 

Builtin op handlers (compiler-emitted CallBuiltin ids) plus the JS standard library (console, Math, JSON, Object, array/string methods) reachable from the host. Handlers pop their arguments off the VM operand stack and return the result value, which the VM pushes back.

Constants

OBJECT_PROTO_METHODS

The Object.prototype methods installed as thunks on the real Object.prototype object, so Object.prototype.toString.call(x) and a class prototype’s inherited hasOwnProperty both resolve through the chain.

REQUIRE_CACHE

The namespace name of the require.cache view. A Builtin rather than an object literal because the module cache is the single source of truth: a populated copy would answer reads correctly and silently ignore a delete, which is the operation the property exists for.

Functions

call_builtin_function

Call a resolved builtin function (global or namespace.method).

call_type_method

Dispatch recv.name(args) for the built-in prototype methods.

construct_builtin

Construct via new for the builtin constructors.

define_property_pub

[[DefineOwnProperty]] reachable from crate::proxy’s no-trap forward.

delete_property

[[Delete]] (10.1.10) for an already-resolved property key: the one place delete o[k], delete o.k and Reflect.deleteProperty all go through, so the three cannot drift. Reports false for a non-configurable property (sloppy mode ignores the failure rather than throwing) and true otherwise, which is also what deleting an absent key reports.

dynamic_function

Build a callable from a complete function-expression source text — the ONE dynamic-function generator on this frontend.

error_string

A short Name: message string for an error value (used when an await rejection unwinds as a thrown error).

eval_source

eval(src). direct selects the scope the source runs in: a DIRECT eval — the literal eval(...) call form — evaluates in the CALLER’s scope, every other route to the same function value is an INDIRECT eval and evaluates in the global scope (ECMA-262 19.2.1.1 PerformEval). The two are told apart in host::call_named, which ops::CALL reaches and ops::CALL_VALUE/APPLY do not.

function_builtin_method

Function.prototype methods (call/apply/bind) plus Symbol.prototype/ generator handling done elsewhere. Returns Ok(None) if name is not one of these (so the caller can try statics).

function_ctor

new Function(p1, …, pN, body) / Function(p1, …, pN, body).

get_property

get_property_recv

[[Get]](name, receiver) — 10.1.8. receiver is the object the read STARTED from and is what a getter sees as this; it differs from recv only when the read was forwarded down a prototype chain, which is why Reflect.get(t, k, r) and a Proxy get trap’s third argument both need it. Every ordinary read passes recv itself.

has_property

key in obj respecting the prototype chain. Reports a Result because a Proxy’s has trap is user code and may throw.

install

Register every node-js builtin id on a VM.

is_known_builtin

is_object_builtin_method

namespace_property

A property on a builtin namespace object (Math.PI, Number.MAX_SAFE_INTEGER, console.log).

numeric_hook

Host callback for arithmetic fusevm cannot complete natively (a non-Int/ non-Float operand). Supplies JavaScript + concatenation and coercion.

object_builtin_method

Dispatch an Object.prototype builtin method on an object/instance.

own_descriptor_pub

[[GetOwnProperty]] reachable from crate::proxy’s no-trap forward.

private_brand_message

The TypeError a failed private brand check raises. Node words it two ways: a private METHOD or accessor names the class the receiver should have been an instance of, while a private FIELD names the member.

proto_method

Dispatch a @proto:<Ctor>:<method> thunk (a method read off a builtin prototype, e.g. Object.prototype.toString) against recv (its invoke-time this). Object.prototype.toString yields the [object Tag] brand string libraries type-check on; every other method routes through normal method dispatch on recv.

prototype_of

[[GetPrototypeOf]] (10.1.1) — the answer Object.getPrototypeOf, Reflect.getPrototypeOf and a __proto__ READ all have to agree on.

set_property_pub

[[Set]] reachable from crate::proxy’s no-trap forward, which has to land on the same path a plain o.k = v takes.
