View Source Unsubscribing
To unsubscribe, you can simply use the schema/type or the label in the same way that you did for subscribing. So if you subscribe like so:
EctoWatch.subscribe({User, :inserted})
EctoWatch.subscribe({User, :updated}, {:role_id, role.id})
EctoWatch.subscribe(:user_contact_info_updated)
You can unsubscribe like so (respectively):
EctoWatch.unsubscribe({User, :inserted})
EctoWatch.unsubscribe({User, :updated}, {:role_id, role.id})
EctoWatch.unsubscribe(:user_contact_info_updated)
