Structs§

  • DOMTracker 🔒
  • MutableWeakRef 🔒
    A mutable weak reference to a JS-managed DOM object. On tracing, the contained weak reference is dropped if the pointee was already collected.
  • WeakBox
    The inner box of weak references, public for the finalization in codegen.
  • WeakRef
    A weak reference to a JS-managed DOM object.
  • WeakRefEntry 🔒
    An entry of a vector of weak references. Passed to the closure given to WeakRefVec::update.
  • WeakRefVec 🔒
    A vector of weak references. On tracing, the vector retains only references which still point to live objects.

Constants§

  • DOM_WEAK_SLOT
    The index of the slot wherein a pointer to the weak holder cell is stored for weak-referenceable bindings. We use slot 1 for holding it, this is unsafe for globals, we disallow weak-referenceable globals directly in codegen.
