Enum StepState 

#[non_exhaustive]
pub enum StepState {
    Idle,
    Pending,
    Done,
}

Where the field step unit stands after Scene::field_step.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Idle

No Eager field was due, so no unit was opened.

Pending

A unit is open, with candidates left to compute.

Done

This step computed the unit’s last candidates and applied it.
