What problem does this feature solve?

So there is this project that allows you to use rspack in your cypress tests which would be the best case as we can use a unified toolchain across our projects. Unfortunately it is only for rspack and not for rsbuild which I use. It would be great if there is a JavaScript function or something else that converts rsbuild to rspack. I guess the functionality must be already implemented if rspack is called by rsbuild.

What does the proposed API look like?

convertToRspackConfig(yourRsbuildOptions)
