pub fn set_server_url(url: &'static str)Expand description
Set the root server URL that all server function paths are relative to for the client.
If this is not set, it defaults to the origin.
This may be called more than once; the most recent value wins. Requests read the URL as they are built, so a change applies to the next server function call. Clients that talk to more than one backend can switch between them without restarting the process.
