serve

Runs the app until it is stopped: SIGINT or SIGTERM (when config.handle_signals), or shutdown(*app) from another thread. One scheduler per config.threads (default: the processor count), each with its own listener on the same port. Returns once the servers have stopped; the error says why it could not start (the port is taken, two routes conflict, the TLS configuration is unusable) and is .NONE for a clean stop.

hello :: () -> string {
    return "hello";
}

main :: () {
    app: App;
    defer free_app(*app);

    get(*app, "/hello", hello);

    error := serve(*app);   // returns after Ctrl-C
    if error.kind != .NONE print("%\n", error_text(error));
}

serve :: (app: *App) -> Serve_Error
