Struct script::dom::bindings::refcounted::LiveDOMReferences

pub struct LiveDOMReferences {
    reflectable_table: RefCell<HashMap<*const c_void, Weak<TrustedReference>>>,
    promise_table: RefCell<HashMap<*const Promise, Vec<Rc<Promise>>>>,
}

The set of live, pinned DOM objects that are currently prevented from being garbage collected due to outstanding references.

Fields

reflectable_table: RefCell<HashMap<*const c_void, Weak<TrustedReference>>>

promise_table: RefCell<HashMap<*const Promise, Vec<Rc<Promise>>>>

Implementations

impl LiveDOMReferences

pub fn initialize()

Set up the thread-local data required for storing the outstanding DOM references.

pub fn destruct()

fn addref_promise(&self, promise: Rc<Promise>)

unsafe fn addref(&self, ptr: *const c_void) -> Arc<TrustedReference>

ptr must be a pointer to a type that implements DOMObject. This is not enforced by the type system to reduce duplicated generic code, which is acceptable since this method is internal to this module.
