Struct JavascriptExceptionRealm 

pub struct JavascriptExceptionRealm { /* private fields */ }

Realm class identities used to classify arbitrary JavaScript thrown values.

Error subclasses and ordinary objects are registered by managed identity; primitives use only the realm’s declared canonical classes.

Implementations

impl JavascriptExceptionRealm

pub fn new( undefined_class: ClassRef, null_class: ClassRef, boolean_class: ClassRef, number_class: ClassRef, bigint_class: ClassRef, string_class: ClassRef, object_class: ClassRef, ) -> Self

Declare the canonical primitive and ordinary-object classes for a realm.

pub fn register_managed_class(&mut self, object: ManagedHandle, class: ClassRef)

Associate an ordinary object with its exact realm class (including subclasses).

pub fn raise( &self, cx: &Cx, value: JavascriptValue, origin: Origin, ) -> KernelResult<Raised>

Wrap an arbitrary thrown value in the one shared exceptional-completion envelope.

pub fn thrown_value<'a>( &self, raised: &'a Raised, ) -> Option<&'a JavascriptValue>

Recover the exact JavaScript value retained by this realm’s envelope.
