Struct SeenRoutes

struct SeenRoutes {
    seen: HashSet<RouteKey>,
}

Routes this connection has already been warned about.

A client that publishes into thin air, or sends a payload the schema does not permit, rarely does it once, so reporting every message would bury the log. Reporting also stops past SeenRoutes::CAP distinct routes, so a client cycling through topics cannot turn a warning into unbounded memory or log volume. One tracker per kind of warning, so a noisy route of one kind does not hide the other.

Fields

seen: HashSet<RouteKey>
