Enum StepDisposition 

pub enum StepDisposition {
    Effects(EffectsDisposition),
    Terminal(TerminalDisposition),
}

What a single committed step publishes.

A union, not a record with an optional terminal beside an effect list: “terminal and terminal observations land in the same committed step, and that step publishes no effect” is then a property of the type, not of every caller remembering to clear the other field.

Variants

Effects(EffectsDisposition)

Terminal(TerminalDisposition)
