这是一个框架用于在Haskell中远程过程调用。

特性：

• 用法非常简单

• 调用一个远程方法是类型安全的Calling a remote procedure is type safe.

• Modal logic inspired worlds, aka hosts:

  • Services run from the World IO monad, written Host w => WIO w
  • This allows world specific actions: if one world will be compiled to JS and one to x86, we could have the following types
  </li> </ul>

      putStrLn :: IO_World w => WIO w a     installTextBox :: JS_World w => WIO w () 

  • Arbitrily complex remote procedures:
    • Rather than only being able to call a remote function of one argument, we can call with any number of arguments
    </li> </ul>

        foo :: (Sendable a1 ,..., Sendable aN, Sendable b, Host w) => a1 -> ... -> aN -> WIO w b 

    • It can send pure functions across the wire and now garbage collect them.

        instance (Serializable a) => Sendable a a           instance (Sendable a' a, Sendable b b') => Sendable (a -> b) (a' -> IO b') 

    • Only local code can execute

      • unlike some modal logic aproaches to mobile languages, the only code that can be executed is the code you compiled, and not code passed from world to world
      </li>

    • State can be serialized with references.

    </ul>
