#### Description [src]

    final class Dex.Promise : GObject.TypeInstance
    {
      /* No available fields */
    }

`DexPromise` is a convenient `DexFuture` for prpoagating a result or rejection in appliction and library code.

Use this when there is not a more specialized `DexFuture` for your needs to propagate a result or rejection to the caller in an asynchronous fashion.
