Well-known symbols

View Source 
var ErrVMUnwinding = errors.New("VM unwinding")

ErrVMUnwinding is a sentinel error that indicates the VM is unwinding with an exception. When this error is returned, the caller should abort and return vm.Undefined immediately (without returning an error) to let the exception continue to propagate.

Functions

func ObjectGetOwnPropertyDescriptorForHarness 

func ObjectGetOwnPropertyDescriptorForHarness(obj vm.Value, name vm.Value) (vm.Value, error)

ObjectGetOwnPropertyDescriptorForHarness exposes a minimal descriptor getter for the test262 harness

func SetupTypedArrayConstructorProperties added in v0.9.9 

func SetupTypedArrayConstructorProperties(ctor vm.Value, proto *vm.PlainObject, bytesPerElement int)

SetupTypedArrayConstructorProperties sets up the constructor properties with correct descriptors. Per ECMAScript spec: - BYTES_PER_ELEMENT: { writable: false, enumerable: false, configurable: false } - prototype: { writable: false, enumerable: false, configurable: false } - length: { writable: false, enumerable: false, configurable: true } - value is 3

func SetupTypedArrayPrototype 

func SetupTypedArrayPrototype(proto *vm.PlainObject, vmInstance *vm.VM)

SetupTypedArrayPrototype adds common TypedArray prototype methods to the given prototype object. This should be called after setting up the type-specific properties.

func SetupTypedArrayPrototypeProperties added in v0.9.9 

func SetupTypedArrayPrototypeProperties(proto *vm.PlainObject, vmInstance *vm.VM, bytesPerElement int)

SetupTypedArrayPrototypeProperties sets up the prototype properties with correct descriptors. Per ECMAScript spec: - BYTES_PER_ELEMENT: { writable: false, enumerable: false, configurable: false } Note: buffer, byteLength, byteOffset, length accessors are on %TypedArray%.prototype (base), not on each subtype prototype. See typedarray_base_init.go.

func SetupTypedArrayToStringTag added in v0.9.9 

func SetupTypedArrayToStringTag(proto *vm.PlainObject, typedArrayName string)

SetupTypedArrayToStringTag adds Symbol.toStringTag getter to a TypedArray prototype. Per ECMAScript spec, %TypedArray%.prototype[@@toStringTag] is "TypedArray" and each specific TypedArray prototype has its own [@@toStringTag] (e.g., "Uint8Array"). The property is: { writable: false, enumerable: false, configurable: true }

func TypedArrayGPFC added in v0.9.10 

func TypedArrayGPFC(vmInstance *vm.VM) error

TypedArrayGPFC calls GetPrototypeFromConstructor if newTarget is set. This implements the GPFC portion of AllocateTypedArray.

func TypedArrayToIndex added in v0.9.10 

func TypedArrayToIndex(vmInstance *vm.VM, arg vm.Value) (int, error)

TypedArrayToIndex validates a non-object argument for TypedArray constructors. Per spec, ToIndex calls ToNumber which throws TypeError for Symbol and BigInt.

func ValidateTypedArrayBufferAlignment added in v0.9.9 

func ValidateTypedArrayBufferAlignment(vmInstance *vm.VM, buffer *vm.ArrayBufferObject, byteOffset, elementSize int) error

ValidateTypedArrayBufferAlignment checks that when length is undefined (auto-calculate), the remaining buffer bytes after byteOffset is aligned to elementSize. Per ECMAScript spec 22.2.4.5 step 13a: - If bufferByteLength modulo elementSize ≠ 0, throw a RangeError

func ValidateTypedArrayBufferAlignmentShared added in v0.9.9 

func ValidateTypedArrayBufferAlignmentShared(vmInstance *vm.VM, buffer *vm.SharedArrayBufferObject, byteOffset, elementSize int) error

func ValidateTypedArrayByteOffset added in v0.9.9 

func ValidateTypedArrayByteOffset(vmInstance *vm.VM, byteOffsetArg vm.Value, elementSize int) (int, error)

ValidateTypedArrayByteOffset converts byteOffset to integer (calling valueOf if needed) and validates that it's aligned to the element size. Per ECMAScript spec 22.2.4.5: - Step 7: Let offset be ? ToInteger(byteOffset) - Step 10: If offset modulo elementSize ≠ 0, throw a RangeError

func ValidateTypedArrayByteOffsetShared added in v0.9.9 

func ValidateTypedArrayByteOffsetShared(vmInstance *vm.VM, byteOffsetArg vm.Value, elementSize int) (int, error)
