pub fn build_from_file() -> (ConfigDrivenApp, Vec<JoinHandle<()>>)Expand description
Build a ConfigDrivenApp from rws.config.toml and spawn L4/WS proxy
threads. Returns the app and a list of background thread handles.
Problems ProxyConfig::validate finds are printed first (the same
findings rws --check reports). The returned app reloads its routes when
the configuration is reloaded (SIGHUP, POST /admin/config/reload) —
see ConfigDrivenApp::reload_from_file.
