#include <v8.h>
Represents the microtask queue, where microtasks are stored and processed. https://html.spec.whatwg.org/multipage/webappapis.html#microtask-queue https://html.spec.whatwg.org/multipage/webappapis.html#enqueuejob(queuename,-job,-arguments) https://html.spec.whatwg.org/multipage/webappapis.html#perform-a-microtask-checkpoint
A MicrotaskQueue instance may be associated to multiple Contexts by passing it to Context::New(), and they can be detached by Context::DetachGlobal(). The embedder must keep the MicrotaskQueue instance alive until all associated Contexts are gone or detached.
Use the same instance of MicrotaskQueue for all Contexts that may access each other synchronously. E.g. for Web embedding, use the same instance for all origins that share the same URL scheme and eTLD+1.

◆ ~MicrotaskQueue()
◆ MicrotaskQueue()
◆ AddMicrotasksCompletedCallback()
Adds a callback to notify the embedder after microtasks were run. The callback is triggered by explicit RunMicrotasks call or automatic microtasks execution (see Isolate::SetMicrotasksPolicy).
Callback will trigger even if microtasks were attempted to run, but the microtasks queue was empty and no single microtask was actually executed.
Executing scripts inside the callback will not re-trigger microtasks and the callback.
◆ EnqueueMicrotask() [1/2]
Enqueues the callback to the queue.
◆ EnqueueMicrotask() [2/2]
Enqueues the callback to the queue.
◆ GetMicrotasksScopeDepth()

Returns the current depth of nested MicrotasksScope that has kRunMicrotasks.
◆ IsRunningMicrotasks()

Returns true if a microtask is running on this MicrotaskQueue instance.

Runs microtasks if no microtask is running on this MicrotaskQueue instance.
