// This class wraps the promise resolver to simplify creation of
// ContentDecryptionModuleResult objects. The default implementations of the
// complete(), completeWithSession(), etc. methods will reject the promise
// with an error. It needs to be subclassed and the appropriate complete()
// method overridden to resolve the promise as needed.
//
// Subclasses need to keep a Member<> to the object that created them so
// that the creator remains around as long as this promise is pending. This
// promise is not referenced by the object that created it (e.g MediaKeys,
// MediaKeySession, Navigator.requestMediaKeySystemAccess), so this promise
// may be cleaned up before or after it's creator once both become unreachable.
// If it is after, the destruction of the creator may trigger this promise,
// so use isValidToFulfillPromise() to verify that it is safe to fulfill
// the promise.
