◆ Cleanup()

static V8_WARN_UNUSED_RESULT Maybe<bool> Cleanup ( Local< FinalizationGroup finalization_group)
static

Runs the cleanup callback of the given FinalizationGroup.

V8 will inform the embedder that there are finalizer callbacks be called through HostCleanupFinalizationGroupCallback.

HostCleanupFinalizationGroupCallback should schedule a task to call FinalizationGroup::Cleanup() at some point in the future. It's the embedders responsiblity to make this call at a time which does not interrupt synchronous ECMAScript code execution.

If the result is Nothing<bool> then an exception has occurred. Otherwise the result is |true| if the cleanup callback was called successfully. The result is never |false|.
