pub fn entered<S>(
routes: Router<S>,
arrival: Arrival,
origins: &ListenerOrigins,
) -> Router<S>Expand description
routes behind the entry decision of the listener origins names:
every route of the table arrives as arrival, and an OPTIONS
request at any of them is judged as a preflight. The remote listener
puts its sockets and its page behind this (wire D56); the city’s own
table layers each route itself, because its routes arrive as
different kinds.
