Class Method Details

.run(app, host:, port:, count: 1) ⇒ Object

Runs the app the way falcon host does: declare a server environment, hand it to Async::Service::Controller. The controller binds the socket once in the parent, runs count supervised workers accepting from it (restarts, health checks, INT/TERM/HUP handling all come with it).
