// Generic-slots are pure slots that can be hooked up to signals. They're
// mainly intended to be used in tests where we want to check if a signal
// was invoked and what arguments were passed. NOTE: They do not do any
// lifetime management of the arguments received via callbacks.
//
// Example:
//   /* Some signal */
//   sigslot::signal1<int> foo;
//
//   /* We want to monitor foo in some test */
//   rtc::GenericSlot1<int> slot(&foo, 0);
//   foo.emit(5);
//   EXPECT_TRUE(slot.callback_received());
//   EXPECT_EQ(5, *(slot.arg1()));
