Enum Step 

pub enum Step<Ph = Never, R = Never> {
    Continue,
    Goto(Ph),
    Stop(R),
}

The become verdict (Agha 1986): what replaces the current behavior as it processes one event.

Variants

Continue

Keep the current behavior; poll for the next event.

Goto(Ph)

Transition to another phase from the menu (no-op when already there).

Stop(R)

Stop after this reaction, with the carried reason.
