Enum RejectEffect 

#[non_exhaustive]
pub enum RejectEffect {
    Applied,
    SameState,
    HeldDown,
    Kept,
    NotNextHop,
}

What Table::apply_reject did.

It is #[non_exhaustive], so a new effect isn’t a breaking change: a match needs a wildcard arm.

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.

Applied

It changed a learned route’s state.

SameState

Nothing to change: no route, a direct one, or the state already in effect.

HeldDown

It would change the route, but came within the hold-down of the last change from the same arrival port.

Kept

For a learned route, with a reason other than 1 or 2, which changes no route (Clause 6.6.3.5).

NotNextHop

For a learned route through another router than the reject’s sender, under the router’s next-hop policy (#1698): the router didn’t apply it. Table::apply_reject itself never returns this.
