Outcome

rmut_session

Enum Outcome 

Source 
pub enum Outcome {
    Done,
    Ask(Ask),
    Front(FrontOp),
}
Expand description

What came of running a function.

Variants§

§

Done

The session did it. Whatever there was to say went out as a Notice; whatever the front end must do next is waiting in Session::take_request.

§

Ask(Ask)

It cannot finish without an answer. The front end collects one however it likes and hands it back to Session::answer.

§

Front(FrontOp)

Only the front end can do this one.
