Overview

Dramatis::Futures are proxy objects for the values returned from actor method calls made with future continuations. When a method is called on a future, the runtime checks to see if the future has been evaluated and returned from the actor that executed the task. If it has, the method is executed on the returned value as if the proxy object was not there.

If the task with the future continuation has not yet completed or the continuation task has not yet been run, the method called on the proxy is suspended until the reply is received. Thus, methods on futures sometimes but not always block. If they block, they have normal continuation gating semantics.

Dramatis::Future has no user-callable methods (except for the implicit method_missing). Other future operations are available through the Dramatis::Future::Interface object, accessible via Dramatis.interface.
