Event

Enum Event 

Source
#[non_exhaustive]
pub enum Event { Route { id: Id<Route>, kind: ChangeKind, }, Interface { id: Id<Interface>, kind: ChangeKind, }, Neighbor { id: Id<NeighborEntry>, kind: ChangeKind, }, Address { id: Id<InterfaceAddress>, kind: ChangeKind, }, ResyncRequired { domain: EventDomain, }, }
Expand description

A signal that something changed in the system’s networking state — carrying an ID and a ChangeKind, not a clone of the full domain object.

Deliberately signal-shaped rather than snapshot-shaped (e.g. Event::Route { id, kind }, not Event::RouteAdded(Route)): native change notifications frequently don’t hand over the full object in the first place (an RTM_NEWROUTE message or a Windows route-change callback can carry only what changed, not a complete record), and a consumer that only cares that something changed before deciding whether to re-query it shouldn’t pay for a clone of the full object on every event. A consumer that needs the current value re-reads it through the relevant provider (Lattice::routes(), keyed by the ID carried here).

#[non_exhaustive]: DNS resolver configuration changes are a stated long-term goal for this enum (see ARCHITECTURE.md) but are not emitted by any backend yet — no platform in Stage 0.8 exposes a push notification for /etc/resolv.conf/per-adapter DNS settings changing without resorting to filesystem polling, which isn’t a genuine push signal. Adding a Dns variant later is not a breaking change for consumers who already match non-exhaustively.

Variants (Non-exhaustive)§

This enum is marked as 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.

ResyncRequired

Notifications were dropped because the bounded queue filled; re-read the indicated domain before relying on later signals.
