Fields

reflector_: Reflector

connections: DomRefCell<HashMapTracedValues<DBName, HashMapTracedValues<Uuid, Dom<IDBOpenDBRequest>>>>

https://www.w3.org/TR/IndexedDB-2/#connection The connections opened through this factory. We store the open request, which contains the connection. TODO: remove when we are sure they are not needed anymore.

indexeddb_transactions: DomRefCell<HashMapTracedValues<DBName, Vec<Dom<IDBTransaction>>>>

https://www.w3.org/TR/IndexedDB-3/#transaction Active transactions associated with this factory’s global.

callback: DomRefCell<Option<GenericCallback<ConnectionMsg>>>

Implementations

pub(crate) fn maybe_commit_txn(&self, db_name: &str, txn_serial: u64)

pub(crate) fn clear_open_request_transaction_for_txn( &self, transaction: &IDBTransaction, )

https://w3c.github.io/IndexedDB/#dom-idbrequest-transaction Clear IDBOpenDBRequest.transaction once the upgrade transaction is finished.

pub fn new(global: &GlobalScope, can_gc: CanGc) -> DomRoot<IDBFactory>

fn get_or_setup_callback(&self) -> GenericCallback<ConnectionMsg>

Setup the callback to the backend service, if this hasn’t been done already.

Trait Implementations

impl DomObject for IDBFactory

type ReflectorType = ()

fn reflector(&self) -> &Reflector<Self::ReflectorType>

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for IDBFactory

const WRAP: unsafe fn(&mut JSContext, &GlobalScope, Option<HandleObject<'_>>, Box<Self>) -> Root<Dom<Self>> = {script_bindings::codegen::GenericBindings::IDBFactoryBinding::Wrap::<dom::bindings::codegen::DomTypeHolder::DomTypeHolder> as for<'a, 'b, 'c> unsafe fn(&'a mut js::context::JSContext, &'b dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'c, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::indexeddb::idbfactory::IDBFactory>) -> script_bindings::root::Root<script_bindings::root::Dom<dom::indexeddb::idbfactory::IDBFactory>>}

Function pointer to the general wrap function type

impl Drop for IDBFactory

fn drop(&mut self)

Executes the destructor for this type.

impl HasParent for IDBFactory

fn as_parent(&self) -> &Reflector

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Reflector

impl IDBFactoryMethods<DomTypeHolder> for IDBFactory

fn Open( &self, name: DOMString, version: Option<u64>, ) -> Fallible<DomRoot<IDBOpenDBRequest>>

https://w3c.github.io/IndexedDB/#dom-idbfactory-open

fn DeleteDatabase(&self, name: DOMString) -> Fallible<DomRoot<IDBOpenDBRequest>>

https://www.w3.org/TR/IndexedDB/#dom-idbfactory-deletedatabase

fn Databases(&self, cx: &mut JSContext) -> Rc<Promise>

https://www.w3.org/TR/IndexedDB/#dom-idbfactory-databases

fn Cmp( &self, cx: &mut JSContext, first: HandleValue<'_>, second: HandleValue<'_>, ) -> Fallible<i16>

https://www.w3.org/TR/IndexedDB-2/#dom-idbfactory-cmp

impl IDLInterface for IDBFactory

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for IDBFactory

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl MutDomObject for IDBFactory

unsafe fn init_reflector<Actual>(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq for IDBFactory

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToJSValConvertible for IDBFactory

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

fn safe_to_jsval(&self, cx: &mut JSContext, rval: MutableHandle<'_, Value>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl Traceable for IDBFactory

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
