Expand description
A collection of microtasks in FIFO order.

§microtask_queue: DomRefCell<Vec<Microtask>>
The list of enqueued microtasks that will be invoked at the next microtask checkpoint.

Implementations§
source§impl MicrotaskQueue
impl MicrotaskQueue
sourcepub fn enqueue(&self, job: Microtask, cx: JSContext)
pub fn enqueue(&self, job: Microtask, cx: JSContext)
Add a new microtask to this queue. It will be invoked as part of the next microtask checkpoint.
sourcepub fn checkpoint<F>(
&self,
cx: JSContext,
target_provider: F,
globalscopes: Vec<Root<Dom<GlobalScope>>>,
)
pub fn checkpoint<F>( &self, cx: JSContext, target_provider: F, globalscopes: Vec<Root<Dom<GlobalScope>>>, )
https://html.spec.whatwg.org/multipage/#perform-a-microtask-checkpoint Perform a microtask checkpoint, executing all queued microtasks until the queue is empty.
