Enum Flow 

pub enum Flow<T> {
    Continue,
    Done(T),
    Cancel,
    Ignored,
    Handoff(Command),
}

What a component wants after handling an event.

Variants

Continue

Keep going. The view is rendered again, and repainted only if it changed.

Done(T)

Finished with a value.

Cancel

The user backed out (Escape, q): no value.

Ignored

The event was not for this component: it is left to the container the component is in, which may use it itself (a focus key, a binding of its own) or pass it on to its own container (0.0.14). The event loop, at the top, treats it as Continue.

Handoff(Command)

Give the terminal to command ($EDITOR file, a pager) until it exits, then take it back and repaint; the component then gets Event::Returned with the exit code (#489).
