How to use Unix soket for Rspack Dev Server?

I am trying a complex project configuration where Rspack is being used. The Dev Server will run behind the proxy and thus need to use Unix-like socket as opposed to default TCP port.

I have been already using Webpack DevServer with Unix sockets using devServer.ipc field. How can I do the same using Rspack dev server? I am not able to find any documentation for similar functionality.

Note: It is also okay if I need to manage it via programmatic API.

rspack-dev-server uses webpack-dev-server internally and proxies devServer.ipc to it...

Link to doc in repo

import { Configuration } from '@rspack/cli';
const config: Configuration = {
  // ...
  devServer: {
        ipc: true,
        //ipc: '/tmp/socket_name.sock',
  },
};
export default config;
