VertxExecutionContext

A scala scala.concurrent.ExecutionContext binds scala.concurrent.Promise/scala.concurrent.Future to a thread. In the case of Vert.x we have to make sure that they execute on the right context. A context could be that of a worker or a standard verticle. This execution context implementation runs all Runnables on the associated io.vertx.core.Context.
