Scheduler usage
O-Community
I'd like to make use of the scheduler so that I can check login status on a thread, and set up the realm once logged in on the main thread.
I'm using `Scheduler::invoke` on a scheduler created with `Scheduler::make_default()`. Is there something I'm missing?
```cpp
auto scheduler = realm::util::Scheduler::make_default();
std::thread loginThread ([this, username, scheduler]()
{
try
{
std::future_status status;
// TODO: Improve security with JWT based login
std::string credentials = "{ \"username\": \"" + username + "\" }";
std::cout << "Logging in..." << std::endl;
auto userFuture = app->login (realm::App::credentials::function (credentials));
std::cout << "Waiting for response" << std::endl;
do
{
switch (status = userFuture.wait_for (50ms); status)
{
case std::future_status::deferred:
std::cout << "deferred\n";
break;
case std::future_status::timeout:
std::cout << "timeout\n";
break;
case std::future_status::ready:
std::cout << "ready!\n";
break;
}
} while (status != std::future_status::ready);
user = userFuture.get();
std::cout << "Logged in. User ID is " << user.identifier() << '\n';
scheduler->invoke ([this]
{
setupSyncedRealm();
setupSubscriptions();
setupObservers();
});
}
catch (const realm::app_error& e)
{
std::cout << "Error logging in: " << e.message() << std::endl;
return;
} });
loginThread.detach();
```
