Struct Realm 

pub struct Realm { /* private fields */ }

Representation of a Realm.

In the specification these are called Realm Records.

Implementations

impl Realm

pub fn create(hooks: &dyn HostHooks, root_shape: &RootShape) -> JsResult<Self>

Create a new Realm.

pub fn intrinsics(&self) -> &Intrinsics

Gets the intrinsics of this Realm.

pub fn host_defined(&self) -> GcRef<'_, HostDefined>

Returns an immutable reference to the ECMAScript specification defined \[\[\HostDefined]\] field of the Realm.

Panics

Panics if HostDefined field is mutably borrowed.

pub fn host_defined_mut(&self) -> GcRefMut<'_, HostDefined>

Returns a mutable reference to ECMAScript specification defined \[\[\HostDefined]\] field of the Realm.

Panics

Panics if HostDefined field is borrowed.

pub fn has_class<C: Class>(&self) -> bool

Checks if this Realm has the class C registered into its class map.

pub fn get_class<C: Class>(&self) -> Option<StandardConstructor>

Gets the constructor and prototype of the class C if it is registered in the class map.

pub fn scope(&self) -> &Scope

Returns the scope of this realm.

pub fn register_property<K, V>( &self, key: K, value: V, attribute: Attribute, context: &mut Context, ) -> JsResult<()>

where K: Into<PropertyKey>, V: Into<JsValue>,

Register a property on the global object of this realm.

It will return an error if the property is already defined.

pub fn register_class<C: Class>(&self, spec: StandardConstructor)

Register a class C in this realm.

pub fn unregister_class<C: Class>(&self) -> Option<StandardConstructor>

Unregister a class C in this realm.

Trait Implementations

impl Clone for Realm

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Realm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Realm

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for Realm

impl Finalize for Realm

fn finalize(&self)

Cleanup logic for a type.

impl PartialEq for Realm

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Trace for Realm

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
