Enum IslandingPolicy 

#[non_exhaustive]
pub enum IslandingPolicy {
    Forbidden,
    Allowed,
}

Whether the final topology may split an AC island of the initial topology. An AC island is a set of energized buses joined by in-service branches; HVDC lines do not join islands, and a bus with no in-service branch is an island of its own.

Under either policy the initial topology’s own islands are not a fault: a base network that already has several islands accepts its initial status vector. Under either policy a final topology is refused when it leaves a bus that an in-service generator supplied initially in an island with no in-service generator, because opening branches does not shed load or de-energize buses.

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.

Forbidden

No island of the initial topology may split: the buses of each initial island stay in one island. The final topology may have fewer islands than the initial one, because closing a branch can join them, and islands that are separate initially may stay separate.

Allowed

Islands may split. Each final island gets one reference bus and keeps every load; no load is shed, and a feasible dispatch is not implied.
