Struct GCCallbackFlags 

#[repr(transparent)]
pub struct GCCallbackFlags(pub c_uint);

GCCallbackFlags is used to notify additional information about the GC callback.

• kGCCallbackFlagConstructRetainedObjectInfos: The GC callback is for constructing retained object infos.
• kGCCallbackFlagForced: The GC callback is for a forced GC for testing.
• kGCCallbackFlagSynchronousPhantomCallbackProcessing: The GC callback is called synchronously without getting posted to an idle task.
• kGCCallbackFlagCollectAllAvailableGarbage: The GC callback is called in a phase where V8 is trying to collect all available garbage (e.g., handling a low memory notification).
• kGCCallbackScheduleIdleGarbageCollection: The GC callback is called to trigger an idle garbage collection. GCCallbackFlags is used to notify additional information about the GC callback.
• kGCCallbackFlagConstructRetainedObjectInfos: The GC callback is for constructing retained object infos.
• kGCCallbackFlagForced: The GC callback is for a forced GC for testing.
• kGCCallbackFlagSynchronousPhantomCallbackProcessing: The GC callback is called synchronously without getting posted to an idle task.
• kGCCallbackFlagCollectAllAvailableGarbage: The GC callback is called in a phase where V8 is trying to collect all available garbage (e.g., handling a low memory notification).
• kGCCallbackScheduleIdleGarbageCollection: The GC callback is called to trigger an idle garbage collection.
