@cgranade hmm what do you mean exactly? If you're exposing your Rust code as a CLI app that should already work with NU, no? Or do you mean like shipping an executable that itself runs nutshell on some emulation layer that your Rust app has?
@zpartacoos Neither exactly; more thinking like if you want to provide other interfaces to a shell than a command-line terminal app, similar to the bash or PowerShell kernels for Jupyter.
