Instance Method Summary

Instance Method Details

#after_subscribe(*methods, &block) Also known as: #on_subscribe

This callback will be triggered after the Base#subscribed method is called, even if the subscription was rejected with the Base#reject method.

To trigger the callback only on successful subscriptions, use the Base#subscription_rejected? method:

after_subscribe :my_method, unless: :subscription_rejected?
