#include <userver/drivers/subscribable_futures.hpp>
An adaptor for working with certain external futures.
The SubscribableFuture
must have a Subscribe(Callback)
method that calls the callback when the future is ready. If the future is already ready, then Subscribe
must call the callback immediately. If the promise is dropped and will never be fulfilled properly, then the SubscribableFuture
should call the callback anyway.
